Search Worlds Without End

This much-anticipated second collection of stories is signature Ted Chiang, full of revelatory ideas and deeply sympathetic characters. In "The Merchant and the Alchemist's Gate," a portal through time forces a fabric seller in ancient Baghdad to grapple with past mistakes and the temptation of second chances. In the epistolary "Exhalation," an alien scientist makes a shocking discovery with ramifications not just for his own people, but for all of reality. And in "The Lifecycle of Software Objects," a woman cares for an artificial intelligence over twenty years, elevating a faddish digital pet into what might be a true living being. Also included are two brand-new stories: "Omphalos" and "Anxiety Is the Dizziness of Freedom."

In this fantastical and elegant collection, Ted Chiang wrestles with the oldest questions on earth--What is the nature of the universe? What does it mean to be human?--and ones that no one else has even imagined. And, each in its own way, the stories prove that complex and thoughtful science fiction can rise to new heights of beauty, meaning, and compassion.

Fraa Erasmas is a young avout living in the Concent of Saunt Edhar, a sanctuary for mathematicians, scientists, and philosophers, protected from the corrupting influences of the outside "saecular" world by ancient stone, honored traditions, and complex rituals. Over the centuries, cities and governments have risen and fallen beyond the concent's walls. Three times during history's darkest epochs violence born of superstition and ignorance has invaded and devastated the cloistered mathic community. Yet the avout have always managed to adapt in the wake of catastrophe, becoming out of necessity even more austere and less dependent on technology and material things. And Erasmas has no fear of the outside-the Extramuros-for the last of the terrible times was long, long ago.

Now, in celebration of the week-long, once-in-a-decade rite of Apert, the fraas and suurs prepare to venture beyond the concent's gates-at the same time opening them wide to welcome the curious "extras" in. During his first Apert as a fraa, Erasmas eagerly anticipates reconnecting with the landmarks and family he hasn't seen since he was "collected." But before the week is out, both the existence he abandoned and the one he embraced will stand poised on the brink of cataclysmic change.

Powerful unforeseen forces jeopardize the peaceful stability of mathic life and the established ennui of the Extramuros-a threat that only an unsteady alliance of saecular and avout can oppose-as, one by one, Erasmas and his colleagues, teachers, and friends are summoned forth from the safety of the concent in hopes of warding off global disaster. Suddenly burdened with a staggering responsibility, Erasmas finds himself a major player in a drama that will determine the future of his world-as he sets out on an extraordinary odyssey that will carry him to the most dangerous, inhospitable corners of the planet... and beyond.

One night in July, 2135, there were some eight billion people on Earth. The next morning there were perhaps 400. There was no clue to what had happened to the world's population -- but, over the centuries that followed, still stranger things occurred.

The human lifespan now stretched to millenia instead of decades, and much of the remaining population developed the ability to move at will among the stars -- and abandoned their homeworld for a life in deep space.

Then, after 3000 years, a star-rover discovered what had happened to Earth's original inhabitants -- and that they were coming to reclaim their heritage. Those who had stayed behind knew, with a growing fear, that the mystery of what had been done to Earth and why was about to be solved ... in a way that would change humanity forever.

A sentient Ship with godlike powers (and aspirations) delivers the last survivors of humanity to a horrific, poisonous planet, Pandora--rife with deadly Nerve-Runners, Hooded Dashers, airborne jellyfish, and intelligent kelp. Chaplain/Psychiatrist Raja Lon Flattery is brought back out of hybernation to witness Ship's machinations as well as the schemes of human scientists manipulating the genetic structure of humanity. Sequel to Frank Herbert's Destination: Void, the first book in Herbert & Ransom's Pandora Sequence.

2045-2059. Human society continues to evolve on Datum Earth, its battered and weary origin planet, as the spread of humanity progresses throughout the many Earths beyond.

Lobsang, now an elderly and complex AI, suffers a breakdown, and disguised as a human attempts to live a "normal" life on one of the millions of Long Earth worlds. His old friend, Joshua, now in his fifties, searches for his father and discovers a heretofore unknown family history. And the super-intelligent post-humans known as "the Next" continue to adapt to life among "lesser" humans.

But an alarming new challenge looms. An alien planet has somehow become "entangled" with one of the Long Earth worlds and, as Lobsang and Joshua learn, its voracious denizens intend to capture, conquer, and colonize the new universe - the Long Earth - they have inadvertently discovered.

Spensa's life as a Defiant Defense Force pilot has been far from ordinary. She proved herself one of the best starfighters in the human enclave of Detritus and she saved her people from extermination at the hands of the Krell--the enigmatic alien species that has been holding them captive for decades. What's more, she traveled light-years from home as an undercover spy to infiltrate the Superiority, where she learned of the galaxy beyond her small, desolate planet home.

Now, the Superiority--the governing galactic alliance bent on dominating all human life--has started a galaxy-wide war. And Spensa's seen the weapons they plan to use to end it: the Delvers. Ancient, mysterious alien forces that can wipe out entire planetary systems in an instant. Spensa knows that no matter how many pilots the DDF has, there is no defeating this predator.

Except that Spensa is Cytonic. She faced down a Delver and saw something eerily familiar about it. And maybe, if she's able to figure out what she is, she could be more than just another pilot in this unfolding war. She could save the galaxy.

The only way she can discover what she really is, though, is to leave behind all she knows and enter the Nowhere. A place from which few ever return.

Valis is the first book in Philip K. Dick's incomparable final trio of novels (the others being are The Divine Invasion and The Transmigration of Timothy Archer).

This disorienting and bleakly funny work is about a schizophrenic hero named Horselover Fat; the hidden mysteries of Gnostic Christianity; and reality as revealed through a pink laser. Valis is a theological detective story, in which God is both a missing person and the perpetrator of the ultimate crime.

Thomas Carmody wins the Intergalactic Sweepstakes and leaves Earth behind. He ends up following his fast-talking Prize from place to place, seeing talking dinosaurs, a perfect city smothering its residents with motherly love, a giant slightly bored God and much more. The only problem is that Death is chasing closely after him and there seems to be no way to get safely home...

God is not dead, he has merely been exiled to an extraterrestrial planet. And it is on this planet that God meets Herb Asher and convinces him to help retake Earth from the demonic Belial. Featuring virtual reality, parallel worlds, and interstellar travel, The Divine Invasion blends philosophy and adventure in a way few authors can achieve.

As the middle novel of Dick's VALIS trilogy, The Divine Invasion plays a pivotal role in answering the questions raised by the first novel, expanding that world while exploring just how much anyone can really know--even God himself.

A science fiction mystery from the author of THE HARVEST, in which a small American town vanishes, and its inhabitants wake up one morning in a world strangely different from their own - a world of curfews, rationing and secret police.

All those who ever lived on Earth have found themselves resurrected--healthy, young, and naked as newborns--on the grassy banks of a mighty river, in a world unknown. Miraculously provided with food, but with no clues to the meaning of their strange new afterlife, billions of people from every period of Earth's history--and prehistory--must start again.

Sir Francis Bacon would be the first to glimpse the incredible way-station, a link between worlds. This forbidden sight would spur the renowned 19th-century explorer to uncover the truth. Along with a remarkable group of compatriots, including Alice Liddell Hargreaves (the Victorian girl who was the inspiration for Alice in Wonderland), an English-speaking Neanderthal, a WWII Holocaust survivor, and a wise extraterrestrial, Burton sets sail on the magnificent river. His mission: to confront humankind's mysterious benefactors, and learn the true purpose--innocent or evil--of the Riverworld...

It is the fourteenth century and one of the most apocalyptic events in human history is set to occur - the coming of the Black Death. History teaches us that a third of Europe's population was destroyed. But what if? What if the plague killed 99 percent of the population instead? How would the world have changed? This is a look at the history that could have been - a history that stretches across centuries, a history that sees dynasties and nations rise and crumble, a history that spans horrible famine and magnificent innovation. These are the years of rice and salt.

This is a universe where the first ship to reach the New World travels across the Pacific Ocean from China and colonization spreads from west to east. This is a universe where the Industrial Revolution is triggered by the world's greatest scientific minds - in India. This is a universe where Buddhism and Islam are the most influential and practiced religions and Christianity is merely a historical footnote.

Through the eyes of soldiers and kings, explorers and philosophers, slaves and scholars, Robinson renders an immensely rich tapestry. Rewriting history and probing the most profound questions as only he can, Robinson shines his extraordinary light on the place of religion, culture, power, and even love on such an Earth. From the steppes of Asia to the shores of the Western Hemisphere, from the age of Akbar to the present and beyond, here is the stunning story of the creation of a new world.

Resurrected on the lush, mysterious banks of Riverworld, along with the rest of humanity, Samuel Langhorne Clemens (a.k.a. Mark Twain) has a dream: to build a riverboat that will rival the most magnificent paddle-wheelers ever navigated on the mighty Mississippi. Then, to steer it up the endless waterway that dominates his new home planet--and at last discover its hidden source.

But before he can carry out his plan, he first must undertake a dangerous voyage to unearth a fallen meteor. This mission would require striking an uneasy alliance with the bloodthirsty Viking Erik Bloodaxe, treacherous King John of England, legendary French swordsman Cyrano de Bergerac, Greek adventurer Odysseus, and the infamous Nazi Hermann Göring. All for the purpose of storming the ominous stone tower at the mouth of the river, where the all-powerful overseers of Riverworld--and their secrets--lie in wait...

It's been nearly 200 years since the collapse of the Confederacy, the last government to claim humanity's colonies. So when signals come in revealing lost human colonies that could shift the power balance, the race is on between the Caliphate ships and a small team of scientists and mercenarys. But what awaits them all is a threat far beyond the scope of any human government.

Fleeing the city of New York on the TransContinental atmospheric transport vehicle, Dran Florrian is traveling with Palimpsest -- the ultimate proof of a lifetime of scientific theorizing.

When a rogue organization attempts to steal the device, however, Dran takes drastic action.

But his invention threatens to destroy the very fabric of this and all other possible universes, unless Dran -- or someone very much like him -- can shut down the machine and reverse the process.

Years have passed on Riverworld. Entire nations have risen, and savage wars have been fought--all since the dead of Earth found themselves resurrected in their magnificent new homeworld. Yet the truth about the Ethicals, the powerful engineers of this mysterious "afterlife," remains unknown. But a curious cross-section of humanity is determined to change that situation... at any cost.

Intrepid explorer Sir Richard Francis Burton leads the most remarkable voyage of discovery he has ever undertaken. Hot on his heels are Samuel Clemens, King John of England, and Cyrano de Bergerac. Spurred by the promise of ultimate answers, they chart a course across the vast polar sea--and toward the awesome tower that looms above it. But getting there will be more than half the battle. For death on Riverworld has become chillingly final...

A generation after the events of The Long Earth, humankind has spread across the new worlds opened up by "stepping." A new "America" - Valhalla - is emerging more than a million steps from Datum - our Earth. Thanks to a bountiful environment, the Valhallan society mirrors the core values and behaviors of colonial America. And Valhalla is growing restless under the controlling long arm of the Datum government.

Soon Joshua, now a married man, is summoned by Lobsang to deal with a building crisis that threatens to plunge the Long Earth into a war unlike any humankind has waged before.

The answers behind the enigmatic origins of Riverworld lie at last within reach, as the remarkable gathering of Earthlings--including Sir Richard Francis Burton, Samuel Clemens, Alice Liddell Hargreaves (the real-life Alice in Wonderland), Cyrano de Bergerac, Ulysses S. Grant, and Baron Von Richtoven--finally breaches the stronghold of Riverworld's extraordinary super-race.

But answers would lead to more enigmatic questions...

Who is the Mysterious Stranger who taunted the Riverworld resurrectees with hints of the truth? What is the key to the gargantuan computer that wields the power of life and death? The astonishing secrets lie within the Dark Tower--but only for those brave enough to seek them and wise enough to decipher them...

Thirty-five billion people from throughout Earth's history were resurrected along the great and winding waterways of Riverworld. Most began life anew--accepting without question the sustenance provided by their mysterious benefactors. But a rebellious handful burned to confront the unseen masters who controlled their fate--and these few launched an invasion that would ultimately yield the mind-boggling truth.

Now Riverworld's omnipotent leaders have been confronted, and the renegades of Riverworld--led by the intrepid Sir Richard Francis Burton--control the fantastic mechanism that once ruled them. But the most awesome challenge lies ahead. For in the vast corridors and secret rooms of the tower stronghold, an unknown enemy watches and waits to usurp the usurpers...
