Search Worlds Without End

Europe is crumbling. The Xian Flu pandemic and ongoing economic crises have fractured the European Union, the borderless Continent of the Schengen Agreement is a distant memory, and new nations are springing up everywhere, some literally overnight. For an intelligence officer like Jim, it's a nightmare. Every week or so a friendly power spawns, a new and unknown national entity which may or may not be friendly to England's interests; it's hard to keep on top of it all. But things are about to get worse for Jim. A stabbing on a London bus pitches him into a world where his intelligence service is preparing for war with another universe, and a man has come who may hold the key to unlocking the mystery.

There couldn't be a fire along the Jorgmund Pipe. It was the last thing the world needed. But there it was, burning bright on national television. The Pipe was what kept the Livable Zone safe from the bandits, monsters and nightmares the Go Away War had left in its wake. The fire was a very big problem.

Enter Gonzo Lubitsch and his friends, the Haulage & HazMat Emergency Civil Freebooting Company, a team of master troubleshooters who roll into action when things get particularly hot. They helped build the Pipe. Now they have to preserve it—and save humanity yet again. But this job is not all it seems. It will touch more closely on Gonzo's life, and that of his best friend, than either of them can imagine. And it will decide the fate of the Gone-Away World.

Multiverse travel is finally possible, but there's just one catch: No one can visit a world where their counterpart is still alive. Enter Cara, whose parallel selves happen to be exceptionally good at dying – from disease, turf wars, or vendettas they couldn't outrun. Cara's life has been cut short on 372 worlds in total.

On this dystopian Earth, however, Cara has survived. Identified as an outlier and therefore a perfect candidate for multiverse travel, Cara is plucked from the dirt of the wastelands. Now what once made her marginalized has finally become an unexpected source of power. She has a nice apartment on the lower levels of the wealthy and walled-off Wiley City. She works – and shamelessly flirts – with her enticing yet aloof handler, Dell, as the two women collect off-world data for the Eldridge Institute. She even occasionally leaves the city to visit her family in the wastes, though she struggles to feel at home in either place. So long as she can keep her head down and avoid trouble, Cara is on a sure path to citizenship and security.

But trouble finds Cara when one of her eight remaining doppelgängers dies under mysterious circumstances, plunging her into a new world with an old secret. What she discovers will connect her past and her future in ways she could have never imagined – and reveal her own role in a plot that endangers not just her world, but the entire multiverse.

The 21st century was on the brink of nuclear confrontation when the 300 kilometer-long stone flashed out of nothingness and into Earth's orbit. NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.

For the Stone was from space--but perhaps not our space; it came from the future--but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...

And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow. But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.

Multiple Nebula and Hugo Award-winner Greg Bear returns to the Earth of his acclaimed novel Eon—a world devastated by nuclear war. The crew of the asteroid-starship Thistledown has thwarted an attack by the Jarts by severing their link to the Way, an endless corridor that spans universes. The asteroid settled into orbit around Earth and the tunnel snaked away, forming a contained universe of its own.

Forty years later, on Gaia, Rhita Vaskayza recklessly pursues her legacy, seeking an Earth once again threatened by forces from within and without. For physicist Konrad Korzenowski, murdered for creating The Way, and resurrected, is compelled by a faction determined to see it opened once more. And humankind will discover just how entirely they have underestimated their ancient adversaries.

Seventy-five years from today, the human race has been cast from a dying Earth to wander the stars in a vast fleet of arks--each shaped by its inhabitants into a diverse and fascinating new environment, with its own rules and eccentricities.

When her sister disappears while responding to a mysterious alien distress call, Eryn insists on being part of the crew sent to look for her. What she discovers on Candidate-623 is both terrifying and deadly. When the threat follows her back to the fleet and people start dying, she is tasked with seeking out a legendary recluse who may just hold the key to humanity's survival.

A hero is missing. The post-apocalyptic wasteland is awash with violence and injustice, and the genrenaut's own King must step in and show precisely why There Will Always be a Max.
