This Day All Gods Die: The Gap into Ruin

The Gap Cycle: Book 5

Stephen R. Donaldson

Stephen R. Donaldson's thrilling Gap series--The Real Story, Forbidden Knowledge, A Dark and Hungry God Arises, and Chaos and Order--introduced us to an adventure as vast as the galaxy and unpredictable as the human heart. It is the work of a storytelling genius with more than ten million copies of his books in print worldwide. Now in this dark, intense story, Donaldson delivers the thrilling conclusion to one of the most powerful science fiction stories ever told.

The countdown has begun. The battleworn crew of Trumpet is in disarray, as they attempt to pursue the pirate ship Soar and her captain Sorus Chatelaine. With one crew member infected by the Amnion and another stranded in the vacuum of space, all their hopes lie with Angus Thermopyle, once a bloodthirsty pirate, now a cyborg working against his will for the United Mining Companies Police--the strongest, most rapacious force in all of human space. As Angus, Morn Hyland, and her force-grown son Davies race for home across the vast reaches of forbidden space, they have no way of knowing that the final confrontation between Warden Dios and The Dragon has begun. Or that the fate of all humankind hangs in the balance.

Blindsight

Blindsight: Book 1

Peter Watts

Two months since the stars fell...

Two months since sixty-five thousand alien objects clenched around the Earth like a luminous fist, screaming to the heavens as the atmosphere burned them to ash. Two months since that moment of brief, bright surveillance by agents unknown.

Two months of silence, while a world holds its breath.

Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route.

So who do you send to force introductions on an intelligence with motives unknown, maybe unknowable? Who do you send to meet the alien when the alien doesn't want to meet?

You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound, so compromised by grafts and splices he no longer feels his own flesh. You send a pacifist warrior in the faint hope she won't be needed, and the fainter one she'll do any good if she is. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist-an informational topologist with half his mind gone-as an interface between here and there, a conduit through which the Dead Center might hope to understand the Bleeding Edge.

You send them all to the edge of interstellar space, praying you can trust such freaks and retrofits with the fate of a world. You fear they may be more alien than the thing they've been sent to find.

But you'd give anything for that to be true, if you only knew what was waiting for them...

Caliban's War

The Expanse: Book 2

James S. A. Corey

We are not alone.

The alien protomolecule is clear evidence of an intelligence beyond human reckoning. No one knows what exactly is being built on Venus, but whatever it is, it is vast, powerful, and terrifying.

When a creature of unknown origin and seemingly impossible physiology attacks soldiers on Ganymede, the fragile balance of power in the Solar System shatters. Now, the race is on to discover if the protomolecule has escaped Venus, or if someone is building an army of super-soldiers.

Jim Holden is the center of it all. In spite of everything, he's still the best man for the job to find out what happened on Ganymede. Either way, the protomolecule is loose and Holden must find a way to stop it before war engulfs the entire system.

CALIBAN'S WAR is an action-packed space adventure following in the footsteps of the critically acclaimed Leviathan Wakes.

James S. A. Corey is a collective pseudonym for authors Daniel Abraham and Ty Franck.

Pandora's Star

Commonwealth Saga: Book 1

Peter F. Hamilton

Critics have compared the engrossing space operas of Peter F. Hamilton to the classic sagas of such sf giants as Isaac Asimov and Frank Herbert. But Hamilton's bestselling fiction--powered by a fearless imagination and world-class storytelling skills--has also earned him comparison to Tolstoy and Dickens. Hugely ambitious, wildly entertaining, philosophically stimulating: the novels of Peter F. Hamilton will change the way you think about science fiction. Now, with Pandora's Star, he begins a new multivolume adventure, one that promises to be his most mind-blowing yet.

The year is 2380. The Intersolar Commonwealth, a sphere of stars some four hundred light-years in diameter, contains more than six hundred worlds, interconnected by a web of transport "tunnels" known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over one thousand light-years away, a star... vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears. Since the location is too distant to reach by wormhole, a faster-than-light starship, the Second Chance, is dispatched to learn what has occurred and whether it represents a threat. In command is Wilson Kime, a five-time rejuvenated ex-NASA pilot whose glory days are centuries behind him.

Opposed to the mission are the Guardians of Selfhood, a cult that believes the human race is being manipulated by an alien entity they call the Starflyer. Bradley Johansson, leader of the Guardians, warns of sabotage, fearing the Starflyer means to use the starship's mission for its own ends,.

Pursued by a Commonwealth special agent convinced the Guardians are crazy but dangerous, Johansson flees. But the danger is not averted. Aboard the Second Chance, Kime wonders if his crew has been infiltrated. Soon enough, he will have other worries. A thousand light-years away, something truly incredible is waiting: a deadly discovery whose unleashing will threaten to destroy the Commonwealth... and humanity itself.

Could it be that Johansson was right?

Judas Unchained

Commonwealth Saga: Book 2

Peter F. Hamilton

Peter F. Hamilton's superbly imagined, cunningly plotted interstellar adventures are conceived on a staggeringly epic scale and filled with fully realized human and alien characters as complex as they are engaging. No mere world builder, Hamilton creates entire universes–and he does so with irresistible flair and intelligence. His previous novel, the acclaimed Pandora's Star, introduced the Intersolar Commonwealth, a star-spanning civilization of the twenty-fourth century. Robust, peaceful, and confident, the Commonwealth dispatched a ship to investigate the mystery of a disappearing star, only to inadvertently unleash a predatory alien species that turned on its liberators, striking hard, fast, and utterly without mercy.

The Prime are the Commonwealth's worst nightmare. Coexistence is impossible with the technologically advanced aliens, who are genetically hardwired to exterminate all other forms of life. Twenty-three planets have already fallen to the invaders, with casualties in the hundreds of millions. And no one knows when or where the genocidal Prime will strike next.

Nor are the Prime the only threat. For more than a hundred years, a shadowy cult, the Guardians of Selfhood, has warned that an alien with mind-control abilities impossible to detect or resist–the Starflyer–has secretly infiltrated the Commonwealth. Branded as terrorists, the Guardians and their leader, Bradley Johansson, have been hunted by relentless investigator Paula Myo. But now evidence suggests that the Guardians were right all along, and that the Starflyer has placed agents in vital posts throughout the Commonwealth–agents who are now sabotaging the war effort. Is the Starflyer an ally of the Prime, or has it orchestrated a fight to the death between the two species for its own advantage?

Caught between two deadly enemies, one a brutal invader striking from without, the other a remorseless cancer killing from within, the fractious Commonwealth must unite as never before.

This will be humanity's finest hour–or its last gasp.

Marooned in Realtime

Across Realtime: Book 2

Vernor Vinge

Nobody knows why there are only three hundred humans left alive on the Earth fifty million years from now. Opinion is fiercely divided on whether to settle in and plant the seed of mankind anew, or to continue using high-energy stasis fields, or "bobbles," in venturing into the future.

When somebody is murdered, it's obvious someone has a secret he or she is willing to kill to preserve.The murder intensifies the rift between the two factions, threatening the survival of the human race. It's up to 21st century detective Wil Brierson, the only cop left in the world, to find the culprit, a diabolical fiend whose lust for power could cause the utter extinction of man.

Filled with excitement and adventure, Vinge's tense SF puzzler will satisfy readers with its sense of wonder and engaging characters, one of whom is a murderer with a unique modus operandi.

The Dark Forest

Remembrance of Earth's Past: Book 2

Cixin Liu

Earth is reeling from the revelation of a coming alien invasion—in just four centuries' time. The aliens' human collaborators may have been defeated, but the presence of the sophons, the subatomic particles that allow Trisolaris instant access to all human information, means that Earth's defense plans are totally exposed to the enemy. Only the human mind remains a secret. This is the motivation for the Wallfacer Project, a daring plan that grants four men enormous resources to design secret strategies, hidden through deceit and misdirection from Earth and Trisolaris alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer and sociologist, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead.

Translated by Joel Martinsen

Note: first published in China in 2008.

Death's End

Remembrance of Earth's Past: Book 3

Cixin Liu

Half a century after the Doomsday Battle, the uneasy balance of Dark Forest Deterrence keeps the Trisolaran invaders at bay. Earth enjoys unprecedented prosperity due to the infusion of Trisolaran knowledge. With human science advancing daily and the Trisolarans adopting Earth culture, it seems that the two civilizations will soon be able to co-exist peacefully as equals without the terrible threat of mutually assured annihilation. But the peace has also made humanity complacent.

Cheng Xin, an aerospace engineer from the early 21st century, awakens from hibernation in this new age. She brings with her knowledge of a long-forgotten program dating from the beginning of the Trisolar Crisis, and her very presence may upset the delicate balance between two worlds. Will humanity reach for the stars or die in its cradle?

The Three-Body Problem

Remembrance of Earth's Past: Book 1

Cixin Liu

Set against the backdrop of China's Cultural Revolution, a secret military project sends signals into space to establish contact with aliens. An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion.

Translation by Ken Liu.

Echopraxia

Blindsight: Book 2

Peter Watts

Prepare for a different kind of singularity in Peter Watts' Echopraxia, the follow-up to the Hugo-nominated novel Blindsight.

It's the eve of the twenty-second century: a world where the dearly departed send postcards back from Heaven and evangelicals make scientific breakthroughs by speaking in tongues; where genetically engineered vampires solve problems intractable to baseline humans and soldiers come with zombie switches that shut off self-awareness during combat. And it's all under surveillance by an alien presence that refuses to show itself.

Daniel Bruks is a living fossil: a field biologist in a world where biology has turned computational, a cat's-paw used by terrorists to kill thousands. Taking refuge in the Oregon desert, he's turned his back on a humanity that shatters into strange new subspecies with every heartbeat. But he awakens one night to find himself at the center of a storm that will turn all of history inside-out.

Now he's trapped on a ship bound for the center of the solar system. To his left is a grief-stricken soldier, obsessed by whispered messages from a dead son. To his right is a pilot who hasn't yet found the man she's sworn to kill on sight. A vampire and its entourage of zombie bodyguards lurk in the shadows behind. And dead ahead, a handful of rapture-stricken monks takes them all to a meeting with something they will only call "The Angels of the Asteroids."

Their pilgrimage brings Dan Bruks, the fossil man, face-to-face with the biggest evolutionary breakpoint since the origin of thought itself.

The Andromeda Strain

Andromeda Strain: Book 1

Michael Crichton

The United States government stands warned that sterilization procedures for returning space probes may be inadequate to guarantee uncontaminated re-entry to the atmosphere. When a probe satellite falls to the earth two years later, and lands in a desolate area of northeastern Arizona, the bodies that lie heaped and flung across the ground, have faces locked in frozen surprise. The terror has begun.

Singularity Sky

Eschaton Series: Book 1

Charles Stross

In the twenty-first century man created the Eschaton, a sentient artificial intelligence. It pushed Earth through the greatest technological evolution ever known, while warning that time travel is forbidden, and transgressors will be eliminated. Distant descendants of this ultra high-tech Earth live in parochial simplicity on the far-flung worlds of the New Republic. Their way of life is threatened by the arrival of an alien information plague known as the Festival. As forbidden technologies are literally dropped from the sky, suppressed political factions descend into revolutionary turmoil. A battle fleet is sent from Earth to destroy the Festival, but Spaceship engineer Martin Springfield and U.N. diplomat Rachel Mansour have been assigned rather different tasks. Their orders are to diffuse the crisis or to sabotage the New Republic's war-fleet, whatever the cost, before the Eschaton takes hostile action on a galactic scale.

Protector

Known Space: Book 5

Larry Niven

Phssthpok the Pak had been traveling for most of his thirty-two thousand years. His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before...

Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days -- Brennan figured to meet that ship first...

He was never seen again -- at least not by those alive at the time.

Night Without Stars

The Chronicle of the Fallers: Book 2

Peter F. Hamilton

After centuries trapped inside the Void, the planet Bienvenido--along with its inhabitants, both human and Faller--has been expelled into normal space. But the survivors are millions of light-years from the Commonwealth, which knows nothing of their existence. As the two races plunge into mortal conflict for sole possession of the planet, the humans seem destined to lose--despite the assistance of the mysterious Warrior Angel, who possesses forbidden Commonwealth technology.

With the Fallers' numbers growing, and their ability to mimic humans allowing them to infiltrate all levels of society, it's only a matter of time before they surge to victory. Then, on a routine space flight, Major Ry Evine inadvertently frees a captive vessel that crash-lands on Bienvenido carrying the last, best hope for human survival: a baby. But a far from ordinary one.

The child not only ages at a remarkable rate but demonstrates knowledge and abilities far beyond those of Bienvenido's humans. Hunted by Fallers and humans alike, she is a crucial link to humanity's lost past--and a glorious future already almost out of reach.

The Fold

Threshold (Clines): Book 2

Peter Clines

STEP INTO THE FOLD.

IT'S PERFECTLY SAFE.

The folks in Mike Erikson's small new England town would say he was just your average, everyday guy. And that's exactly how Mike likes it. Sure, the life he's chosen isn't much of a challenge to someone with his unique gifts, but he's content with his quiet and peaceful existence.

That is, until an old friend presents him with an irresistable mystery, one that Mike is uniquely qualified to solve: far out in the California desert, a team of DARPA scientist has invented a device they affectionately call the Albuquerque Door. Using a cryptic computer equation and magnetic fields to "fold" dimensions, it shrinks distances so a traveler can travel hundreds of feet in a single step.

The invention promises to make mankind's dreams of teleportation a reality. And, the scientists insist, travelling through the Door is completely safe.

Yet evidence is mounting that this miraculous machine isn't quite what it seems -- and that its creators are harboring a dangerous secret.

As his investigation draws him deeper into the puzzle, Mike begins to fear there is only one answer that makes sense, And if he's right, it may be only a matter of time before the project destroys... everything.

Tau Zero

Poul Anderson

Fifty men and women set out in the twenty-third century from Earth aboard an interstellar craft to travel to a planet some thirty light-years away. The ship will approach the speed of light and so (as Einstein predicted) subjective time on board will slow and so the journey of several decades will be of much shorter duration for the crew. But the ship's deceleration system is irreparably damaged when it hits a cloud of interstellar dust and acceleration continues toward light speed, tau zero. Soon the ship is speeding through galaxies and eons are passing on board the ship in the blink of an eye ...

The Abyss Beyond Dreams

The Chronicle of the Fallers: Book 1

Peter F. Hamilton

TO SAVE THEIR CIVILISATION HE MUST DESTROY IT...

When images of a lost civilization are 'dreamed' by a self-proclaimed prophet of the age, Nigel Sheldon, inventor of wormhole technology and creator of the Commonwealth society, is asked to investigate. Especially as the dreams seem to be coming from the Void - a mysterious area of living space monitored and controlled because of its hugely destructive capabilities. With it being the greatest threat to the known universe, Nigel is committed to finding out what really lies within the Void and if there's any truth to the visions they've received. Does human life really exist inside its boundary?

But when Nigel crash lands inside the Void, on a planet he didn't even know existed, he finds so much more than he expected. Bienvenido: a world populated by the ancestors of survivors from Commonwealth colony ships that disappeared centuries ago. Since then they've been fighting an increasingly desperate battle against the Fallers, a space-born predator artificially evolved to conquer worlds. Their sole purpose is to commit genocide against every species they encounter. With their powerful telepathic lure - that tempts any who stray across their path to a slow and painful death - they are by far the greatest threat to humanity's continued existence on this planet.

But Nigel soon realizes that the Fallers also hold the key to something he'd never hoped to find - the destruction of the Void itself. If only he can survive long enough to work out how to use it...

The Gripping Hand

The Moties: Book 2

Larry Niven
Jerry Pournelle

Robert Heinlein called it "possibly the finest science fiction novel I have ever read." The San Francisco Chronicle declared that "as science fiction, The Mote in God's Eye is one of the most important novels ever published." Now Larry Niven and Jerry Pournelle, award winning authors of such bestsellers as Footfall and The Legacy of Heorot, return us to the Mote, and to the universe of Kevin Renner and Horace Bury, of Rod Blaine and Sally Fowler.

There, 25 years have passed since humanity quarantined the mysterious aliens known as Moties within the confines of their own solar system. They have spent a quarter century analyzing and agonizing over the deadly threat posed by the only aliens mankind has ever encountered-- a race divided into distinct biological forms, each serving a different function. Master, Mediator, Engineer. Warrior. Each supremely adapted to its task, yet doomed by millions of years of evolution to an inescapable fate. For the Moties must breed-- or die. And now the fragile wall separating them and the galaxy beyond is beginning to crumble.

Earth Unaware

Ender's Universe: First Formic War: Book 1

Orson Scott Card
Aaron Johnston

The mining ship El Cavador is far out from Earth, in the deeps of the Kuiper Belt, beyond Pluto. Other mining ships, and the families that live on them, are few and far between this far out. So when El Cavador's telescopes pick up a fast-moving object coming in-system, it's hard to know what to make of it. It's massive and moving at a significant fraction of the speed of light.

El Cavador has other problems. Their systems are old and failing. The family is getting too big for the ship. There are claim-jumping corporate ships bringing Asteroid Belt tactics to the Kuiper Belt. Worrying about a distant object that might or might not be an alien ship seems...not important.

They're wrong. It's the most important thing that has happened to the human race in a million years. The first Formic War is about to begin.

Earth Awakens

Ender's Universe: First Formic War: Book 3

Orson Scott Card
Aaron Johnston

The story of The First Formic War continues in Earth Awakens.

Nearly 100 years before the events of Orson Scott Card's bestselling novel Ender's Game, humans were just beginning to step off Earth and out into the Solar System. A thin web of ships in both asteroid belts; a few stations; a corporate settlement on Luna. No one had seen any sign of other space-faring races; everyone expected that First Contact, if it came, would happen in the future, in the empty reaches between the stars. Then a young navigator on a distant mining ship saw something moving too fast, heading directly for our sun.

When the alien ship screamed through the solar system, it disrupted communications between the far-flung human mining ships and supply stations, and between them and Earth. So Earth and Luna were unaware that they had been invaded until the ship pulled into Earth orbit, and began landing terra-forming crews in China. Politics and pride slowed the response on Earth, and on Luna, corporate power struggles seemed more urgent than distant deaths. But there are a few men and women who see that if Earth doesn't wake up and pull together, the planet could be lost.

The Ophiuchi Hotline

Eight Worlds: Book 1

John Varley

After the effortless capture of Earth by vastly superior aliens, humanity is forced to fight for existence on the Moon and other lumps of airless rock. The invention of the Hotline -- a constant stream of data from a star in the constellation Ophiuchus -- facilitates survival and enables the development of amazing new technologies.

Then, after 400 years, humanity's unknown helpers send a bill for their services... and suddenly everything is threatened once again.

The Ophiuchi Hotline was John Varley's first novel, and it received nominations for both the Hugo and Nebula awards he later won both for his book Persistence of Vision.

Earth Afire

Ender's Universe: First Formic War: Book 2

Orson Scott Card
Aaron Johnston

One hundred years before Ender's Game, the aliens arrived on Earth with fire and death. This is the story of the First Formic War.

Victor Delgado beat the alien ship to Earth, but just barely. Not soon enough to convince skeptical governments that there was a threat. They didn't believe that until space stations and ships and colonies went up in sudden flame.

And when that happened, only Mazer Rackham and the Mobile Operations Police could move fast enough to meet the threat.

Sphere

Michael Crichton

In the middle of the South Pacific, a thousand feet below the surface of the water, a huge vessel is discovered resting on the ocean floor. It is a spaceship of phenomenal dimensions, apparently undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old.

But even more fantastic—and frightening—is what waits inside . . .

The Cassini Division

The Fall Revolution: Book 3

Ken MacLeod

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.

Raising Caine

Tales of the 22nd Century: Book 3

Charles E. Gannon

Caine Riordan, reluctant diplomatic and military intelligence operative, has just finished playing his part repulsing the Arat Kur's and Hkh'Rkh's joint invasion of Earth.

But scant hours after the attackers surrender, the mysterious but potentially helpful Slaasriithi appeal to Caine to shepherd a diplomatic mission on a visit to their very alien worlds. The possible prize: a crucial alliance in a universe where the fledgling Consolidated Terran Republic has very few friends.

But Caine and his legation aren't the only ones journeying into the unknown reaches of Slaasriithi space. A group of renegade K'tor are following them, hoping to destroy humanity's hopes for a quick alliance. And that means finding and killing Caine Riordan.

Assuming that the bizarre and dangerous Slaasriithi lifeforms don't do it first.

The Swarm

Ender's Universe: Second Formic War: Book 1

Orson Scott Card
Aaron Johnston

Orson Scott Card and Aaron Johnston return to their Ender's Game prequel series with this first volume of an all-new trilogy about the Second Formic War in The Swarm.

The first invasion of Earth was beaten back by a coalition of corporate and international military forces, and the Chinese army. China has been devastated by the Formic's initial efforts to eradicate Earth life forms and prepare the ground for their own settlement. The Scouring of China struck fear into the other nations of the planet; that fear blossomed into drastic action when scientists determined that the single ship that wreaked such damage was merely a scout ship.

There is a mothership out beyond the Solar System's Kuiper Belt, and it's heading into the system, unstoppable by any weapons that Earth can muster.

Earth has been reorganized for defense. There is now a Hegemon, a planetary official responsible for keeping all the formerly warring nations in line. There's a Polemarch, responsible for organizing all the military forces of the planet into the new International Fleet. But there is an enemy within, an enemy as old as human warfare: ambition and politics. Greed and self-interest. Will Bingwen, Mazer Rackam, Victor Delgado and Lem Juke be able to divert those very human enemies in time to create a weapon that can effectively defend humanity in the inexorable Second Formic War?

The Last Theorem

Arthur C. Clarke
Frederik Pohl

The final work from the brightest star in science fiction's galaxy. Arthur C Clarke, who predicted the advent of communication satellites and author of 2001: A Space Odyssey completes a lifetime career in science fiction with a masterwork.

30 light years away, a race known simply as the One Point Fives are plotting a dangerous invasion plan, one that will wipe humankind off the face of the Earth...

Meanwhile, in Sri Lanka, a young astronomy student, Ranjit Subramanian, becomes obsessed with a three-hundred-year-old theorem that promises to unlock the secrets of the universe. While Ranjit studies the problem, tensions grow between the nations of the world and a UN taskforce headed up by China, America and Russia code-named Silent Thunder begins bombing volatile regimes into submission.

On the eve of the invasion of Earth a space elevator is completed, helped in part by Ranjit, which will herald a new type of Olympics to be held on the Moon. But when alien forces arrive Ranjit is forced to question his own actions, in a bid to save the lives of not just his own family but of all of humankind.

Co-written with fellow grand master Frederik Pohl, The Last Theorem not only provides a fitting end to the career one of the most famous names in science fiction but also sets a new benchmark in contemporary prescient science fiction. It tackles with ease epic themes as diverse as third world poverty, the atrocities of modern warfare in a post-nuclear age, space elevators, pure mathematics and mankind's first contact with extra-terrestrials.
