Search Worlds Without End

From junkies who drink at the time-stream to love affairs in time-reversed galaxies; from gene-altered dolphins that converse only in limericks to the program that allows you to design your own child; from the brain implants called axiomatics to the strange attractors that spin off new religions, Greg Egan's future is frighteningly close to our own present.

For fifteen years, Earth has had a scientific station on an exoplanet orbiting Gliese 876, humanity's only presence outside the Solar System. But a new and powerful telescope at L5 can detect no evidence of Phaeton Base, even though it should be able to do so. So the US has sent Colonel Bradley Elliott, USAF, to investigate. Twenty years before, Elliott was the first, and to date only, man to land on the Martian surface. What he discovered there gave the US the stars, but it might also be responsible for the disappearance of Phaeton Base...

It is April 1962. The Korean War has escalated and the US is struggling to keep the Russians and Chinese north of the 38th parallel. All the men are away fighting, but that doesn't mean the Space Race is lost. NASA decides to look elsewhere for its astronauts: the thirteen women pilots who passed the same tests as the original male candidates. These are the Mercury 13: Jerrie Cobb, Janey Hart, Myrtle Cagle, Jerri Sloan, Jan Dietrich, Marion Dietrich, Bernice Steadman, Wally Funk, Sarah Gorelick, Gene Nora Stumbough, Jean Hixson, Rhea Hurrle and Irene Leverton. One of these women will be the first American in space. Another will be the first American to spacewalk. Perhaps one will even be the first human being to walk on the Moon. Beneath the surface of the Atlantic Ocean, deep in the Puerto Rico Trench north of San Juan, lies a film bucket from a KH-4 Corona spy satellite. It should have been caught in mid-air by a C-130 from the 6549th Test Group. That didn't happen. So the US Navy bathyscaphe Trieste II must descend twenty thousand feet to retrieve the bucket, down where light has never reached and the pressure is four tons per square inch. But there is more in the depths than anyone had expected, much more. This is not our world. But it very nearly was.

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.

Forty-one years ago the renowned physicist Chris Robin vanished. Before his disappearance, his fringe science theories about the existence of endless alternate universes had earned him both admirers and enemies.

Alex Benedict and Chase Kolpath discover that Robin had several interstellar yachts flown far outside the planetary system where they too vanished. And following Robin's trail into the unknown puts Benedict and Kolpath in danger...

Anthologies seldom make history, but Dangerous Visions is a grand exception. Harlan Ellison's 1967 collection of science fiction stories set an almost impossibly high standard, as more than a half dozen of its stories won major awards - not surprising with a contributors list that reads like a who's who of 20th-century SF.

Reynolds' pursuit of truth is not limited to wide-angle star smashing - not that stars don't get pulverised when one character is gifted (or cursed) with an awful weapon by the legendary Merlin. Reynolds' protagonists find themselves in situations of betrayal, whether by a loved one's accidental death, as in 'Signal to Noise', or by a trusted wartime authority, in 'Spirey and the Queen'. His fertile imagination can resurrect Elton John on Mars in 'Understanding Space and Time' or make prophets of the human condition out of pool-cleaning robots in the title story. But overall, the stories in ZIMA BLUE represent a more optimistic take on humanity's future, a view that says there may be wars, there may be catastrophes and cosmic errors, but something human will still survive.

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.

Ray Bradbury is a modern cultural treasure. His disarming simplicity of style underlies a towering body of work unmatched in metaphorical power by any other American storyteller. And here, presented in a new trade edition, are thirty-two of his most famous tales--prime examples of the poignant and mysterious poetry which Bradbury uniquely uncovers in the depths of the human soul, the otherwordly portraits of outré fascination which spring from the canvas of one of the century's great men of imagination.

From a lonely coastal lighthouse to a sixty-million-year-old safary, from the pouring rain of Venus to the ominous silence of a murder scene, Ray Bradbury is our sure-handed guide not only to surprising and outrageous manifestations of the future, but also to the wonders of the present that we could never have imagined on our own.

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.

Three hundred years in the future, Verity Auger is a specialist in the archaeological exploration of Earth, rendered uninhabitable after the technological catastrophe known as the Nanocaust. After a field-trip to goes badly wrong, Verity is forced to redeem herself by participating in a dangerous mission, for which her expertise in invaluable.

Using a backdoor into an unstable alien transit system, Auger's faction has discovered something astonishing at the far end of a wormhole: mid twentieth-century Earth, preserved like a fly in amber. Is it a window into the past, a simulation, or something else entirely?

CENTURY RAIN is not just a time-travel story, nor a tale of alternate history. Part hard SF thriller, part interstellar adventure, part noir romance, CENTURY RAIN is something altogether stranger.

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.

Prisoner of New Half-Way Tree

It's Carnival time and the Caribbean-colonized planet of Toussaint is celebrating with music, dance, and pageantry. Masked "Midnight Robbers" waylay revelers with brandished weapons and spellbinding words. But to young Tan-Tan, the Robber Queen is simply a favorite costume to wear at the festival -- until her power-corrupted father commits an unforgivable crime.

Suddenly, both father and daughter are thrust into the brutal world of New Half-Way Tree. Here monstrous creatures from folklore are real, and the humans are violent outcasts in the wilds. Here Tan-Tan must reach into the heart of myth -- and become the Robber Queen herself. For only the Robber Queen's legendary powers can save her life... and set her free.

Jacob Kelley's family is turned upside down when an old friend turns up, waving a gun and babbling about an alien quantum intelligence. The mystery deepens when the friend is found dead in an underground bunker... apparently murdered the night he appeared at Jacob's house. Jacob is arrested for the murder and put on trial.

As the details of the crime slowly come to light, the weave of reality becomes ever more tangled, twisted by a miraculous new technology and a quantum creature unconstrained by the normal limits of space and matter. With the help of his daughter, Alessandra, Jacob must find the true murderer before the creature destroys his family and everything he loves.

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.

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.

Only a few know the terrifying truth--an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun. They know the truth--but who will listen? They have foreseen the cost of abundant energy--but who will believe? These few beings, human and alien, hold the key to the Earth's survival.

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.

In Beggars and Choosers, Kress returns to the same future world created in her earlier work, an America strangely altered by genetic modifications...

Most of the world is on the verge of collapse, overburdened by a population of jobless drones and racked by the results of irresponsible genetic research and nanotechnology. Will the world be saved? And for whom?

Picoverse: a universe one million-millionth of our own, created by deliberately ripping apart the fabric of space-time.

A big-bang of an adventure, Robert Metzger's Picoverse boldly embraces the grand traditions of the genre, while exploding beyond the limits of knowledge, beyond the edges of the imagination, and beyond the boundaries of the universe as we know it.

"Probably the most daring SF novel since Ringworld...mind-boggling." (F. Paul Wilson, author of All the Rage)

"Bob Metzger knows his science. He proves it in Picoverse, a complex and intriguing story that ranges widely through time and space." (Charles Sheffield, author of The Spheres of Heaven)

"Metzger has captured the essence of that good old time religion SF fans have worshiped since the genre began: a rousing hard SF tale with a true Sense of Wonder...This one is a winner." (David A. Truesdale, Editor, SFWA Bulletin)

"A 21st century leap from the physics lab into the multiverse that only Gregory Benford, Philip José Farmer, and A.E. Van Vogt could have written-if they had ever collaborated." (Tom Easton, Reviewer, Analog)

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.

The astonishing new SF novel from multi-award winning author Stephen Baxter - a dizzying exploration of alternate universes and deep time.

Fresh from his latest collaboration with Terry Pratchett on the Long Earth sequence Stephen Baxter now returns to the mysteries and challanges first hinted at in his acclaimed novel PROXIMA.

In PROXIMA we discovered ancient alien artifacts on the planet of Per Ardua - hatches that allowed us to step across light years of space as if we were stepping into another room. The universe opened up to us. Now in ULTIMA the consequences of this new freedom make themselves felt. And we discover that there are minds in the universe that are billions of years old and they have a plan for us. For some of us. But as we learn the true nature of the universe we also discover that we have countless pasts all meeting in this present and that our future is terrifyingly finite. It's time for us to fight to take back control.

This is grand scale, big idea SF of the best possible sort. It is set to build on the massive success of PROXIMA and define Stephen Baxter's work going forward.

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.

Aboard the hyperspace liner Redshift, the first sign of trouble is the apparent suicide of a passenger. When first officer Jason Kraft discovers that she was murdered, Kraft wants to know why. Before long, a desperate group of people tries to use the hyperspace craft for their evil purposes, and Kraft is the only person in their way.

From the PASSENGER GUIDE. WARNING: Read This Guide Before Boarding the Redshift.

The environment aboard a hyperspace craft is quite safe as long as you are careful. The management reminds you that the speed of light on board this craft is ten meters per second, or about 30 million times slower than what you are used to. This means you will frequently encounter relativistic effects and optical illusions...

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.

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.

Everett Singh has escaped with the Infundibulum from the clutches of Charlotte Villiers and the Order, but at a terrible price. His father is missing, banished to one of the billions of parallel universes of the Panoply of All Worlds, and Everett and the crew of the airship Everness have taken a wild Heisenberg jump to a random parallel plane. Everett is smart and resourceful, and from the refuge of a desolate frozen Earth far beyond the Plenitude, where he and his friends have gone into hiding, he makes plans to rescue his family. But the villainous Charlotte Villiers is one step ahead of him.

The action traverses three different parallel Earths: one is a frozen wasteland; one is just like ours, except that the alien Thryn Sentiency has occupied the Moon since 1964, sharing its technology with humankind; and one is the embargoed home of dead London, where the remnants of humanity battle a terrifying nanotechnology run wild. Across these parallel planes of existence, Everett faces terrible choices of morality and power. But he has the love and support of Sen, Captain Anastasia Sixsmyth, and the rest of the crew of Everness as he learns that the deadliest enemy isn't the Order or the world-devouring nanotech Nahn - it's himself.

World-hopping, high-action adventure starring a smart boy with computer skills and a tough girl who pilots a blimp

The airship Everness makes a Heisenberg Jump to an alternate Earth unlike any her crew has ever seen. Everett, Sen, and the crew find themselves above a plain that goes on forever in every direction without any horizon. There they find an Alderson Disc, an astronomical megastructure of incredibly strong material reaching from the orbit of Mercury to the orbit of Jupiter.

Then they meet the Jiju, the dominant species on a plane where the dinosaurs didn't die out. They evolved, diversified, and have a twenty-five million year technology head-start on humanity. War between their kingdoms is inevitable, total and terrible.

Everness has jumped right into the midst of a faction fight between rival nations, the Fabreen and Dityu empires. The airship is attacked, but then defended by the forces of the Fabreen, who offers theEverness crew protection. But what is the true motive behind Empress Aswiu's aid? What is her price?

The crew of the Everness is divided in a very alien world, a world fast approaching the point of apocalypse.

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.

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.
