Search Worlds Without End

Entered by a thousand unsuspected gateways -- built by a race lost in the clouds of time -- the planet its dwellers called the Well World turned beings of every kind into something else. There spacefarer Nathan Brazil found himself companioned by a batman, an amorous female centaur and a mermaid -- all once as human as he.

Yet Nathan Brazil's metamorphosis was more terrifying than any of those...and his memory was coming back, bringing with it the secret of the Well World.

For at the heart of the bizarre planet lay the goal of every being that had ever lived -- and Nathan Brazil and his comrades were...lucky?...enough to find it!

Hartwell and Kathryn Cramer. It is included in the collection Stories of Your Life and Others (2002).

How far should you go to make a profit? Infoquake, the debut novel by David Louis Edelman, takes speculative fiction into alien territory: the corporate boardroom of the far future. Its a stunning trip through the trenches of a technological war fought with product demos, press releases, and sales pitches.

Natch is a master of bio/logics, the programming of the human body. He's clawed and scraped his way to the top of the bio/logics market using little more than his wits. Now his sudden notoriety has brought him to the attention of Margaret Surina, the owner of a mysterious new technology called MultiReal. Only by enlisting Natch's devious mind can Margaret keep MultiReal out of the hands of High Executive Len Borda and his ruthless armies.

To fend off the intricate net of enemies closing in around him, Natch and his apprentices must accomplish the impossible. They must understand this strange new technology, run through the product development cycle, and prepare MultiReal for release to the public all in three days.

Meanwhile, hanging over everything is the specter of the infoquake, a lethal burst of energy that's disrupting the bio/logic networks and threatening to send the world crashing back into the Dark Ages.

With Infoquake, David Louis Edelman has created a fully detailed world that's both as imaginative as Dune and as real as today's Wall Street Journal.

Stories of Your Life and Others presents characters who must confront sudden change--the inevitable rise of automatons or the appearance of aliens--while striving to maintain some sense of normalcy. In the amazing and much-lauded title story, a grieving mother copes with divorce and the death of her daughter by drawing on her knowledge of alien languages and non-linear memory recollection. A clever pastiche of news reports and interviews chronicles a college's initiative to "turn off" the human ability to recognize beauty in "Liking What You See: A Documentary." With sharp intelligence and humor, Chiang examines what it means to be alive in a world marked by uncertainty and constant change, and also by beauty and wonder.

The collection received the Locus Award and the stories have received the Hugo, Seiun, Nebula, and Sturgeon Awards.

A secluded Pacific Northwest cottage becomes a door to the past for Tom Winter, who travels back to the New York City of 1962, followed by a human killing machine that he alone must stop.

Tanner Mirabel was a security specialist who never made a mistake - until the day a woman in his care was blown away by Argent Reivich, a vengeful young postmortal. Tanner's pursuit of Reivich takes him across light-years of space to Chasm City, the domed human settlement on the otherwise inhospitable planet of Yellowstone.

But Chasm City is not what it was. The one-time high-tech utopia has become a Gothic nightmare: a nanotechnological virus has corrupted the city's inhabitants as thoroughly as it has the buildings and machines. Before the chase is done, Tanner will have to confront truths which reach back centuries, towards deep space and an atrocity history barely remembers.

For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Sheldon, creator of the revolutionary science of psychohistory, can see into the future--to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save mankind, Seldon gathers the best minds in the Empire--both scientists and scholars--and brings them to a bleak planet at the edge of the Galaxy to serve as a beacon of hope for a fututre generations. He calls his sanctuary the Foundation.

But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. Mankind's last best hope is faced with an agonizing choice: submit to the barbarians and be overrun--or fight them and be destroyed.

Three strikingly different alien races greeted the military mission from Earth when it reached the planet called Bezer'ej.

Now one of the sentient species has been exterminated -- and two others are poised on the brink of war.

The fragile bezeri are no more, due to the ignorant, desperate actions of human interlopers. The powerful wess'har protectors have failed in their sworn obligation to the destroyed native population -- and the outrage must be redressed.

But those who are coming to judge from the World Before -- the home planet, now distant and alien to the wess'har, whose ancestors left there generations ago -- will not restrict their justice to the individual humans responsible for the slaughter. Earth itself must answer for the genocide. And its ultimate fate may depend on a dead woman: former police officer Shan Frankland, who became something far greater than human before destroying herself in the vast airless depths of space.

Before becoming one of today's most intriguing and innovative mystery writers, Kate Wilhelm was a leading writer of science fiction, acclaimed for classics like The Infinity Box and The Clewiston Test.

Now one of her most famous novels returns to print, the spellbinding story of an isolated post-holocaust community determined to preserve itself, through a perilous experiment in cloning. Sweeping, dramatic, rich with humanity, and rigorous in its science, Where Later the Sweet Birds Sang is widely regarded as a high point of both humanistic and "hard" SF, and won SF's Hugo Award and Locus Award on its first publication. It is as compelling today as it was then.

Identity crises, consumerism, and star-crossed teenage love in a futuristic society where people connect to the Internet via feeds implanted in their brains.

For Titus and his friends, it started out like any ordinary trip to the moon - a chance to party during spring break and play with some stupid low-grav at the Ricochet Lounge. But that was before the crazy hacker caused all their feeds to malfunction, sending them to the hospital to lie around with nothing inside their heads for days. And it was before Titus met Violet, a beautiful, brainy teenage girl who has decided to fight the feed and its omnipresent ability to categorize human thoughts and desires. Following in the footsteps of George Orwell, Anthony Burgess, and Kurt Vonnegut Jr., M. T. Anderson has created a not-so-brave new world — and a smart, savage satire that has captivated readers with its view of an imagined future that veers unnervingly close to the here and now.

In the year 2301, guns are only museum pieces and benign telepaths sweep the minds of the populace to detect crimes before they happen. In 2301 murder is virtually impossible, but one man is about to change that...

Ben Reich, a psychopathic business magnate, has devised the ultimate scheme to eliminate the competition and destroy the order of his society. The Demolished Man is a masterpiece of imaginative suspense, set in a superbly imagined world in which everything has changed except the ancient instinct for murder.

At last, the costly and bitter war between the two Foundations had come to an end. The scientists of the First Foundation had proved victorious; and now they retum to Hari Seldon's long-established plan to build a new Empire that the Second Foundation is not destroyed after all-and that its still-defiant survivors are preparing their revenge. Now the two exiled citizens of the Foundation-a renegade Councilman and the doddering historian-set out in search of the mythical planet Earth. . .and proof that the Second Foundation still exists. Meanwhile someone-or something-outside of both Foundations sees to be orchestrating events to suit its own ominous purpose. Soon representatives of both the First and Second Foundations will find themselves racing toward a mysterious world called Gaia and a final shocking destiny at the very end of the universe!

The continuing epic of Earth's first space colonists--and their fight against a repressive government to reclaim their world in the name of freedom.

Before his trip to the stars, before the Rocinante, Amos Burton was confined to a Baltimore where crime paid you or killed you. Unless the authorities got to you first.

Set in the hard-scrabble solar system of Leviathan Wakes, Caliban's War, Abaddon's Gate and the upcoming Cibola Burn, The Churn expands the world of James S. A. Corey's acclaimed Expanse series. Anthologized in Paula Guran's The Year's Best Science Fiction & Fantasy Novellas 2015.

Born in 2008, Leisha Camden is beautiful, extraordinarily intelligent... and one of an ever-growing number of human beings who have been genetically modified to never require sleep.

Once she and "her kind" were considered interesting anomalies. Now they are outcasts - victims of blind hatred, political repression and shocking mob violence meant to drive the "Sleepless" from human society... and, ultimately, from the Earth itself.M

But Leisha Camden has chosen to remain behind in a world that envies and fears her "gift" - a world marked for destruction in a devastating conspiracy of freedom... and revenge.

An amazing breakthrough in genetic engineering made by Vergil Ulam is considered too dangerous for further research, but rather than destroy his work, he injects himself with his creation and walks out of his lab, unaware of just quite how his actions will change the world. Author Greg Bear's treatment of the traditional tale of scientific hubris is both suspenseful and a compelling portrait of a new intelligence emerging amongst us, irrevocably changing our world.

There is a secret passage through time

...and it leads all the way to the end of Eternity. But the journey has a terrible cost. It alters not only the future but the "present" in which we live.

A century after the publication of H. G. Wells' immortal The Time Machine, Stephen Baxter, today's most acclaimed new "hard SF" author, returns to the distant conflict between the Eloi and the Morlocks in a story that is at once an exciting expansion, and a radical departure based on the astonishing new understandings of quantum physics.

The story of a man with a vision - immortality : for those who can afford it is found in cyberspace. Permutation city is the tale of a man with a vision - how to create immortality - and how that vision becomes something way beyond his control. Encompassing the lives and struggles of an artificial life junkie desperate to save her dying mother, a billionaire banker scarred by a terrible crime, the lovers for whom, in their timeless virtual world, love is not enough - and much more - Permutation city is filled with the sense of wonder.

At the center of the galaxy, a small band of humans, trapped on the barren world of Snowglade and facing extinction, discovers that they will play a new role in the order of the universe.

For thirty years a tiny band of humans has been sheltering in the caverns of an airless, crater-pocked world called Michaelmas. Beyond their solar system lie the ruins of human interstellar civilization, stalked by a ruthless, infinitely patient cybernetic entity determined to root out the last few bands of survivors. One man has guided the people of Michaelmas through the hardest of times, and given them hope against the wolves: Miguel de Ruyter.

When a lone human ship blunders into their system, and threatens to lead the wolves to Michaelmas, de Ruyter embarks on a desperate, near-suicide mission to prevent catastrophe. But an encounter with a refugee from the ship - the enigmatic woman who calls herself only Glass - leads to de Ruyter's world being turned upside down.

In the aftermath of an interstellar war an enigmatic star is discovered, travelling towards the Solar System from the galactic core. Its appearance adds a new and dangerous factor in the turbulent politics of the inhabited worlds as the rival factions - the power-holders of the ReUnited Nations, the rebels who secretly oppose their power, and the Religious Witnesses - all see advantages to be gained. But what awesome technology started the star on its journey half a million years ago - and why?

The passengers on the spaceship Argo, pursued by hostile ""mechs,"" must face their doubts about their captain's obsession with finding the galaxy's True Center, an obsession that even troubles the captain's son.

This multilayered epic of interstellar cabals and dark human passions is a profound exploration of genetics, environment, nurture, society, and the secrets of human intelligence.

In a futuristic world of cybernetics, two young friends become trapped in an endless nightmare of suspicion, surveillance, programmable servants, a centuries-old ruling class, and an enigmatic woman who dominates them all, in a story marked by genius, blackmail, sacrifice, murder, resurrection, the betrayal of innocence, and loyalty stronger than death.

This is the story of Ariane Emory: brilliant, corrupt, a genius in genetics, psychology, rape, and blackmail. She dominates the Council of Nine, as head of the Expansionist Party of the Multiworld Union, and is despot of the territory Reseune, where her laboratories create the one product essential to Cyteen: people. They are the "azi," human workers and soldiers artificially grown, computer trained, and owned by Reseune and hence by Ariane Emory. After one hundred and twenty years of life and fifty years of rule, Emory is murdered. But not for long...

This is the story of the Project: the plan to replicate Ariane Emory. Creatiing a genetic double is routine for Reseune's bio-technology, but nature is not nurture, and clones are still human beings. For the Project to succeed, Emory's followers have to subject the clone to every formative influence of the tyrant's life, keep her innocent of history, protect her from Emory's enemies, and oppress or silence anyone who might, even accidentally, disrupt the program.

This is also the story of Ari: a little girl driven to solve a mystery she can sense, but not define. A child thrown into a storm of global upheaval when her creation is made public, she inherits a stranger’s face and past, enemies and victims. She must wield her predecessor’s power to save herself, even from people she loves. And to survice, she must find out if she’s a puppet crafted by a dead megalomaniac – or the one person who can defuse a socio-genetic time bomb threatening to destroy her planet. For only Ariane Emory can save Cyteen...

This is an omnibus edition of The Heliconia Trilogy.

The planet closest to our Sun, Mercury is a rocky, barren, heat-scorched world. But there are those who hope to find wealth in its desolation.

Saito Yamagata thinks Mercury's position makes it an ideal place to generate power to propel starships into deep space. Astrobiologist Victor Molina thinks the water at Mercury's poles may harbor evidence of life. Bishop Elliot Danvers has been sent by the Earth-based "New Morality" to keep close tabs on Molina.

But all three of these men are blissfully unaware of their shared history, and of how it connects to the collapse of Mance Bracknell's geosynchronous space elevator a generation ago. Now they're about to find out, because Mance is determined to have his revenge...

Geneticist Pierre Tardivel may not have long to live-he's got a fifty-fifty chance of having the gene for Huntington's disease. But if his DNA is tragic, his girlfriend's is astonishing: Molly Bond has a mutation that gives her telepathy. Both of them have attracted the interest of Pierre's boss, Dr. Burian Klimus, a senior researcher in the Human Genome Project who just might be hiding a horrific past. Avi Meyer, a dogged Nazi hunter, thinks Klimus was the monstrous "Ivan the Terrible" of the Treblinka Death Camp.

As Pierre races against the ticking clock of his own DNA to make a world-changing scientific breakthrough, Avi also races against time to bring Klimus to justice before the last survivors of Treblinka pass away.

Ender’s Shadow explores the stars in this all-new novel...

At the end of Shadow of the Giant, Bean flees to the stars with three of his children--the three who share the engineered genes that gave him both hyper-intelligence and a short, cruel physical life. The time dilation granted by the speed of their travel gives Earth’s scientists generations to seek a cure, to no avail. In time, they are forgotten--a fading ansible signal speaking of events lost to Earth’s history. But the Delphikis are about to make a discovery that will let them save themselves, and perhaps all of humanity in days to come.

For there in space before them lies a derelict Formic colony ship. Aboard it, they will find both death and wonders--the life support that is failing on their own ship, room to grow, and labs in which to explore their own genetic anomaly and the mysterious disease that killed the ship’s colony.

A heart-stopping story of love, death, technology, and art set amid the tropics of a futuristic Brazil.

The lush city of Palmares Tres shimmers with tech and tradition, with screaming gossip casters and practiced politicians. In the midst of this vibrant metropolis, June Costa creates art that's sure to make her legendary. But her dreams of fame become something more when she meets Enki, the bold new Summer King. The whole city falls in love with him (including June's best friend, Gil). But June sees more to Enki than amber eyes and a lethal samba. She sees a fellow artist.

Together, June and Enki will stage explosive, dramatic projects that Palmares Tres will never forget. They will add fuel to a growing rebellion against the government's strict limits on new tech. And June will fall deeply, unfortunately in love with Enki. Because like all Summer Kings before him, Enki is destined to die.

Pulsing with the beat of futuristic Brazil, burning with the passions of its characters, and overflowing with ideas, this fiery novel will leave you eager for more from Alaya Dawn Johnson.

George Poole isn't sure whether his life has reached a turning point or a dead end. At forty-five, he is divorced and childless, with a career that is going nowhere fast. Then, when his father dies suddenly, George stumbles onto a family secret: a sister he never knew existed. A twin named Rosa, raised in Rome by an enigmatic cult. Hoping to find the answers to the missing pieces of his life, George sets out for the ancient city.

Once in Rome, he learns from Rosa the enthralling story of their distant ancestor, Regina, an iron-willed genius determined to preserve her family as the empire disintegrates around her. It was Regina who founded the cult, which has mysteriously survived and prospered below the streets of Rome for almost two millennia. The Order, says Rosa, is her real family and, even if he doesn't realize it yet, it is George's family, too. When she takes him into the vast underground city that is the Order's secret home, he feels a strong sense of belonging, yet there is something oddly disturbing about the women he meets. They are all so young and so very much alike.

Stephen Baxter possesses one of the most brilliant minds in modern science fiction. His vivid storytelling skills have earned him comparison to the giants of the past: Clarke, Asimov, Stapledon. Like his great predecessors, Baxter thinks on a cosmic scale, spinning cutting-edge scientific speculation into pure, page-turning gold. Now Baxter is back with a breathtaking adventure that begins during the catastrophic collapse of Roman Britain and stretches forward into an unimaginably distant, war-torn future, where the fate of humanity lies waiting at the center of the galaxy....

"Niven has come up with an idea about as far out as one can get.... This is certainly classic science fiction-the idea is truly the hero." -Asimov's Science Fiction Magazine

When leaving Earth, the crew of the spaceship Discipline was prepared for a routine assignment. Dispatched by the all-powerful State on a mission of interstellar exploration and colonization, Discipline was aided (and secretly spied upon) by Sharls Davis Kendy, an emotionless computer intelligence programmed to monitor the loyalty and obedience of the crew. But what they weren't prepared for was the smoke ring-an immense gaseous envelope that had formed around a neutron star directly in their path. The Smoke Ring was home to a variety of plant and animal life-forms evolved to thrive in conditions of continual free-fall. When Discipline encountered it, something went wrong. The crew abandoned ship and fled to the unlikely space oasis.

Five hundred years later, the descendants of the Discipline crew living on the Smoke Ring no longer remember their origins. Earth is more myth than memory, and no recollection of the State remains. But Kendy remembers. And just outside the Smoke Ring, Discipline waits patiently to make contact with its wayward children.

Nancy Kress cemented her reputation in SF with the publication of her multiple-award-winning novella, "Beggars in Spain," which became the basis for her extremely successful Beggars Trilogy (comprising Beggars in Spain, Beggars and Choosers, and Beggars Ride).

And now she brings us Probability Space, the conclusion of the trilogy that began with Probability Moon and then Probability Sun, which is centered on the same world as Kress's Nebula Award-winning novelette, "Flowers of Aulit Prison." The Probability Trilogy has already been widely recognized as the next great work by this important SF writer.

In Probability Space, humanity's war with the alien Fallers continues, and it is a war we are losing. Our implacable foes ignore all attempts at communication, and they take no prisoners. Our only hope lies with an unlikely coalition: Major Lyle Kaufman, retired warrior Marbet Grant, the Sensitive who's involved with Kaufman Amanda, a very confused fourteen-year-old girl and Magdalena, one of the biggest power brokers in all of human space.

As the action moves from Earth to Mars to the farthest reaches of known space, with civil unrest back home and alien war in deep space, four humans--armed with little more than an unproven theory--try to enter the Fallers' home star system. It's a desperate gamble, and the fate of the entire universe may hang in the balance.

Robert J. Sawyer, the award-winning and bestselling writer, hits the peak of his powers in Humans, the second book of The Neanderthal Parallax, his trilogy about our world and parallel one in which it was the Homo sapiens who died out and the Neanderthals who became the dominant intelligent species. This powerful idea allows Sawyer to examine some of the deeply rooted assumptions of contemporary human civilization dramatically, by confronting us with another civilization, just as morally valid, that has made other choices. In Humans, Neanderthal physicist Ponter Boddit, a character you will never forget, returns to our world and to his relationship with geneticist Mary Vaughan, as cultural exchanges between the two Earths begin.

As we see daily life in another present-day world, radically different from ours, in the course of Sawyer's fast-moving story, we experience the bursts of wonder and enlightenment that are the finest pleasures of science fiction. Humans is one of the best SF novels of the year, and The Neanderthal Parallax is an SF classic in the making.

Life on New Mars is tough for humans, but death is only a minor inconvenience. The machines know their place, the free market rules all, and only the Abolitionists object.

Then a stranger arrives on New Mars, a clone who remember his life on Earth as Jonathan Wilde, the anarchist with a nuclear capability who was accused of losing World War III. This stranger also remembers one David Reid, who now serves as New Mars's leader. Long ago, it turns out, Wilde and Reid had shared ideals and fought over the same women.

Moving from 20th-century Scotland through a tumultuous 21st century and outward to humanity's settlement on a planet circling another star, The Stone Canal is idea-driven sci-fi at its best., making real and believable a future where long lives, strange deaths, and unexpected knowledge await those who survive the wars and revolutions to come.

In the Nevada desert, an experiment has gone horribly wrong. A cloud of nanoparticles—micro-robots—has escaped from the laboratory. This cloud is self-sustaining and self-reproducing. It is intelligent and learns from experience. For all practical purposes, it is alive.

It has been programmed as a predator. It is evolving swiftly, becoming more deadly with each passing hour. Every attempt to destroy it has failed.

And we are the prey.

During all recorded history, the Moon has hovered above our heads, a timeless symbol for lovers' ecstasy. Goddesses and Gibson Girls have tripped the light fantastic of her beams while sonneteers and scientists have scanned her changing phases.

Now man had actually reached the Moon, and on it the explorers found a structure, a formation so terrible and incomprehensible that it couldn't even be described in human terms. It was a thing that devoured men; that killed them again and again in torturous, unfathomable ways.

Earthbound are the only two men who could probe the thing: Al Barker, a homicidal maniac, whose loving mistress was death, and Dr. Edward Hawks, a scientific murderer, whose greatest mission was rebirth.

Plateau, a colony in the Tau Ceti system, was settled by humans some 300 years before the plot begins. The colony world itself is a Venusian type planet with a dense, hot, poisonous atmosphere. It would be otherwise uninhabitable, except for a tall monolithic mesa that rises 40 miles up into a breathable layer in the upper atmosphere. This gives the planet a habitable area about half the size of California. The Captain of the first colony vessel named the feature Mount Lookitthat (from his interjection at first sight of it), and the colony became known as Plateau.

After landing the slower-than-light ships, the Crew sign an agreement, called the Covenant of Planetfall, with their former passengers (who had just emerged from suspended animation and were in a weak bargaining position). This agreement gives the Crew (and their descendants in perpetuity) all control over the new colony. A system of medical care evolves, in which organ transplantation is the only method of treatment, even for cosmetic defects (such as baldness); a justice system evolves, with all crimes punishable by death, followed by involuntary donation of the decedent's transplantable organs (including skin, scalp, and teeth). Not surprisingly, only Colonists are ever arrested for crimes; and only Crew are eligible to receive transplants. Some Colonists become dissatisfied with the system and form a dissident group called the "Sons of Earth."

Ellen May Ngewthu is a young woman with centuries of experience, a soldier and leader of the Cassini Division, the elite defense force of the utopian Solar Union. Here in the twenty-fourth century, the forts of the Division, in orbit around a mysteriously transformed Jupiter, are the front line in humanity's long standoff with the unknowable posthumans--godlike and remote beings descended from the people who transformed themselves with high technology centuries ago.

The posthumans' capacities are unknown . . . but we know they disintegrated Ganymede, we know they punched a wormhole into Jovian space, and we know that the very surface of the solar system's largest planet has been altered by their incomprehensible artifacts. Worst of all, we know that they have been bombarding the solar system with powerful data viruses for generations.

Now Ellen has a plan to rid humanity of this threat once and for all. But she needs to recruit the right people to her cause--and convince them to mistrust the posthumans as much as she does.

Her quest will take her to the mid-Atlantic towers of Solar Union Earth, to the green ruins of London, and, in the farthest reaches of human space, to the long-separated libertarian colony of New Mars. In the process, much will be revealed--about history, about power, and about what it is to be human.

In the free-fall environment of the Smoke Ring, the descendants of the crew of the Discipline no longer remembered their Earth roots -- or the existence of Sharls Davis Kendy, the computer-program despot of the ship. Until Kendy initiated contact once more.

Fourteen years later, only Jeffer, the Citizens Tree Scientist, knew that Kendy was still watching -- and waiting. Then the Citizens Tree people rescued a family of loggers and learned for the first time of the Admiralty, a large society living in free fall amid the floating debris called the Clump. And it was likely that the Admiralty had maintained, intact, Discipline's original computer library.

Exploration was a temptation neither Jeffer nor Kendy could resist, and neither Citizens Tree nor Sharls Davis Kendy would ever be the same again...

Throughout history, man has been searching for better ways to gather information about his universe. But although they may have longed for it, not even the most brilliant minds could conceive of a device as infinitely powerful or as immeasurably precise as the macroscope, until the twenty-first century. By analyzing information carried on macrons, this unbelievable tool brought the whole universe of wonders to man's doorstep. The macroscope was seen by many as the salvation of the human race.

But in the hands of the wrong man, the macroscope could be immensely destructive-infinitely more dangerous than the nuclear bomb. By searching to know too much, man could destroy the very essence of his mind. This is the powerful story of man's struggle with technology, and also the story of his human struggle with himself. This novel takes us across the breathtaking ranges of space as well as through the most touching places in the human heart. It is a story of coming of age, of sacrifice, and of love. It is the story of man's desperate search for a compromise between his mind and his heart, between knowledge and humanity.

When corporations go to war, standard business practice goes out the window. Astro Corporation is led by indomitable Texan Pancho Lane, Humphries Space Systems by the rich and ruthless Martin Humphries, and their fight is over nothing less than resources of the Asteroid Belt itself. As fighting escalates, the lines between commerce and politics, boardroom and bedroom, blur--and the keys to victory will include physics, nanotechnology, and cold hard cash.

As they fight it out, the lives of thousands of innocents hang in the balance, including the rock rats who make their living off the asteroids, and the inhabitants of Selene City on Earth's moon. As if matters weren't complicated enough, the shadowy Yamagata corporation sets its sights on taking advantage of other people's quarrels, and space pirate Lars Fuchs decides it's time to make good on his own personal vendetta.

It's a breakneck finale that can end only in earth's salvation--or the annihilation of all that humankind has ever accomplished in space.

Marak has suffered the madness his entire life. He is a prince and warrior, strong and shrewd and expert in the ways of the desert covering his planet. In the service of his father, he has dedicated his life to overthrowing the Ila, the mysterious eternal dictator of his world. For years he has successfully hidden the visions that plague him -- voices pulling him eastward, calling Marak, Marak, Marak, amid mind-twisting visions of a silver tower. But when his secret is discovered, Marak is betrayed by his own father and forced to march in an endless caravan with the rest of his world's madmen to the Ila's city of Oburan.

Instead of death, Marak finds in Oburan his destiny, and the promise of life -- if he can survive what is surely a suicidal mission. The Ila wants him to discover the source of the voices and visions that afflict the mad. Despite the danger sof the hostile desert, tensions within the caravan, and his own excruciating doubts, Marak miraculously reaches his goal -- only to be given another, even more impossible mission by the strange people in the towers.

According to these beings who look like him yet act differently than anyone he has ever known, Marak has a slim chance to save his world's people from the wrath of Ila's enemies. But to do so, he must convince them all -- warring tribes, villagers, priests, young and old, as well as the Ila herself -- to follow him on an epic trek across the burning desert before the hammer of the Ila's foes falls from the heavens above.

It is the twenty-first century. Earth's space program is thriving, with a colony in place in the Moon. And then an incredible discovery is made on the lunar farside. A massive structure is being erected by living machines--microscopically small, intelligent, unstoppable, consuming whatever they touch. All who come near them die horribly. Meanwhile, the mysterious structure continues to grow, expand, take shape. And its creators begin to multiply....

Is this the first strike in an alien invasion from the stars? Or has human nanotech experimentation gone awry, triggering a long-predicted disaster? As riots rage across a panicked Earth, scientists on Earth and on the Moon race to learn the truth before humanity's home is engulfed by the voracious machines and its inhabitants perish in the most terrifying plague ever known.

At the end of Frank Herbert's final novel, Chapterhouse: Dune, a ship carrying a crew of refugees escapes into the uncharted galaxy, fleeing from a terrifying, mysterious Enemy. The fugitives used genetic technology to revive key figures from Dune's past--including Paul Muad'Dib and Lady Jessica--to use their special talents to meet the challenges thrown at them.

Based directly on Frank Herbert's final outline, which lay hidden in two safe-deposit boxes for a decade, Sandworms of Dune will answer the urgent questions Dune fans have been debating for two decades: the origin of the Honored Matres, the tantalizing future of the planet Arrakis, the final revelation of the Kwisatz Haderach, and the resolution to the war between Man and Machine. This breathtaking new novel in Frank Herbert's Dune series has enough surprises and plot twists to please even the most demanding reader.

When seventeen-year-old Toby McGonigal finds himself lost in space, separated from his family, he expects his next drift into cold sleep to be his last. After all, the planet he's orbiting is frozen and sunless, and the cities are dead. But when Toby wakes again, he's surprised to discover a thriving planet, a strange and prosperous galaxy, and something stranger still - that he's been asleep for 14,000 years.

Welcome to the Lockstep Empire, where civilization is kept alive by careful hibernation. Here cold sleeps can last decades and waking moments mere weeks. Its citizens survive for millenia, traveling asleep on long voyages between worlds. Not only is Lockstep the new center of the galaxy, but Toby is shocked to learn that the Empire is still ruled by its founding family: his own.

Toby's brother Peter has become a terrible tyrant. Suspicious of the return of his long-lost brother, whose rightful inheritance also controls the lockstep hibernation cycles, Peter sees Toby as a threat to his regime. Now, with the help of a lockstep girl named Corva, Toby must survive the forces of this new Empire, outwit his siblings, and save human civilization.

Four men and a woman are reduced to a microscopic fraction of their original size, sent in a miniaturized atomic sub through a dying man's carotid artery to destroy a blood clot in his brain. If they fail, the entire world will be doomed.

Farside, the side of the Moon that never faces Earth, is the ideal location for an astronomical observatory. It is also the setting for a tangled web of politics, personal ambition, love, jealousy, and murder.

Telescopes on Earth have detected an Earth-sized planet circling a star some thirty light-years away. Now the race is on to get pictures of that distant world, photographs and spectra that will show whether or not the planet is truly like Earth, and if it bears life.

Farside will include the largest optical telescope in the solar system as well as a vast array of radio antennas, the most sensitive radio telescope possible, insulated from the interference of Earth's radio chatter by a thousand kilometers of the Moon's solid body.

Building the Farside observatory is a complex, often dangerous task. On the airless surface of the Moon, under constant bombardment of hard radiation and infalling micrometeoroids, builders must work in cumbersome spacesuits and use robotic machines as much as possible. Breakdowns - mechanical and emotional - are commonplace. Accidents happen, some of them fatal.

What they find stuns everyone, and the human race will never be the same.
