But first he will be awakened to become humanity’s unwilling savior. For an alien menace is laying the solar system to waste, and only an anachronism from the days of human barbarism can save an enlightened race….

It was a miracle of science that permitted human beings to live, if not forever, then for a long, long time. Some people, anyway. The rich, the powerful–they lived their lives at the rate of one year every ten. Somec created two societies: that of people who lived out their normal span and died, and those who slept away the decades, skipping over the intervening years and events. It allowed great plans to be put in motion. It allowed interstellar Empires to be built.

It came near to destroying humanity.

After a long, long time of decadence and stagnation, a few seed ships were sent out to save our species. They carried human embryos and supplies, and teaching robots, and one man. The Worthing Saga is the story of one of these men, Jason Worthing, and the world he found for the seed he carried.

Somewhere out beyond the edge of the universe there is a library that contains an infinite number of books, each one the story of another reality. One tells the story of your life as it is, along with another book for the other life you could have lived if you had made a different choice at any point in your life. While we all wonder how our lives might have been, what if you had the chance to go to the library and see for yourself? Would any of these other lives truly be better?

Nora Seed finds herself faced with this decision. Faced with the possibility of changing her life for a new one, following a different career, undoing old breakups, realizing her dreams of becoming a glaciologist; she must search within herself as she travels through the Midnight Library to decide what is truly fulfilling in life, and what makes it worth living in the first place.

Memory makes reality.

That’s what NYC cop Barry Sutton is learning, as he investigates the devastating phenomenon the media has dubbed False Memory Syndrome—a mysterious affliction that drives its victims mad with memories of a life they never lived.

That’s what neuroscientist Helena Smith believes. It’s why she’s dedicated her life to creating a technology that will let us preserve our most precious memories. If she succeeds, anyone will be able to re-experience a first kiss, the birth of a child, the final moment with a dying parent.

As Barry searches for the truth, he comes face to face with an opponent more terrifying than any disease—a force that attacks not just our minds, but the very fabric of the past. And as its effects begin to unmake the world as we know it, only he and Helena, working together, will stand a chance at defeating it.

But how can they make a stand when reality itself is shifting and crumbling all around them?

At once a relentless pageturner and an intricate science-fiction puzzlebox about time, identity, and memory, Recursion is a thriller as only Blake Crouch could imagine it—and his most ambitious, mind-boggling, irresistible work to date.

Jeff Winston was 43 and trapped in a tepid marriage and a dead-end job, waiting for that time when he could be truly happy, when he died.

And when he woke and he was 18 again, with all his memories of the next 25 years intact. He could live his life again, avoiding the mistakes, making money from his knowledge of the future, seeking happiness.

Until he dies at 43 and wakes up back in college again…

Six million years ago, at the very dawn of the starfaring era, Abigail Gentian fractured herself into a thousand male and female clones: the shatterlings. Sent out into the galaxy, these shatterlings have stood aloof as they document the rise and fall of countless human empires. They meet every two hundred thousand years, to exchange news and memories of their travels with their siblings.

Campion and Purslane are not only late for their thirty-second reunion, but they have brought along an amnesiac golden robot for a guest. But the wayward shatterlings get more than the scolding they expect: they face the discovery that someone has a very serious grudge against the Gentian line, and there is a very real possibility of traitors in their midst. The surviving shatterlings have to dodge exotic weapons while they regroup to try to solve the mystery of who is persecuting them, and why – before their ancient line is wiped out of existence, forever.

Four hundred years from now mankind is strung out across a region of interstellar space inherited from an ancient civilization discovered on Mars. The colonies are linked together by the occasional sublight colony ship voyages and hyperspatial data-casting. Human consciousness is digitally freighted between the stars and downloaded into bodies as a matter of course.

But some things never change. So when ex-envoy, now-convict Takeshi Kovacs has his consciousness and skills downloaded into the body of a nicotine-addicted ex-thug and presented with a catch-22 offer, he really shouldn’t be surprised. Contracted by a billionaire to discover who murdered his last body, Kovacs is drawn into a terrifying conspiracy that stretches across known space and to the very top of society.

Some stories cannot be told in just one lifetime. Harry August is on his deathbed. Again. No matter what he does or the decisions he makes, when death comes, Harry always returns to where he began, a child with all the knowledge of a life he has already lived a dozen times before. Nothing ever changes.

Until now. As Harry nears the end of his eleventh life, a little girl appears at his bedside. “I nearly missed you, Doctor August,” she says. “I need to send a message.” This is the story of what Harry does next, and what he did before, and how he tries to save a past he cannot change and a future he cannot allow.

Grad-school dropout Matt Fuller is toiling as a lowly research assistant at MIT when, while measuring subtle quantum forces that relate to time changes in gravity and electromagnetic force, his calibrator turns into a time machine. With a dead-end job and a girlfriend who has left him for another man, Matt has nothing to lose taking a time machine trip himself-or so he thinks.

The Scavenger species are circling. It is, truly, provably, the End Days for the Gzilt civilization.

An ancient people, organized on military principles and yet almost perversely peaceful, the Gzilt helped set up the Culture ten thousand years earlier and were very nearly one of its founding societies, deciding not to join only at the last moment. Now they’ve made the collective decision to follow the well-trodden path of millions of other civilizations; they are going to Sublime, elevating themselves to a new and almost infinitely more rich and complex existence.

Amid preparations though, the Regimental High Command is destroyed. Lieutenant Commander (reserve) Vyr Cossont appears to have been involved, and she is now wanted – dead, not alive. Aided only by an ancient, reconditioned android and a suspicious Culture avatar, Cossont must complete her last mission given to her by the High Command. She must find the oldest person in the Culture, a man over nine thousand years old, who might have some idea what really happened all that time ago.

It seems that the final days of the Gzilt civilization are likely to prove its most perilous.

By the end of the 30th century humanity has the capability to travel the universe, to journey beyond earth and beyond the confines of the vulnerable human frame.

The descendants of centuries of scientific, cultural and physical development divide into fleshers — true Homo sapiens; Gleisner robots — embodying human minds within machines that interact with the physical world; and polises — supercomputers teeming with intelligent software, containing the direct copies of billions of human personalities now existing only in the virtual reality of the polis.

Diaspora is the story of Yatima — a polis being created from random mutations of the Konishi polis base mind seed — and of humankind, Of an astrophysical accident that spurs the thousandfold cloning of the polises. Of the discovery of an alien race and of a kink in time that means humanity — whatever form it takes — will never again be threatened by acts of God.

This is the extraordinary love story of Clare and Henry, who met when Clare was six and Henry was thirty-six, and were married when Clare was twenty-two and Henry was thirty. Impossible but true, because Henry suffers from a rare condition where his genetic clock periodically resets and he finds himself pulled suddenly into his past or future. In the face of this force they can neither prevent nor control, Henry and Clare’s struggle to lead normal lives is both intensely moving and entirely unforgettable.

Bob Johansson has just sold his software company and is looking forward to a life of leisure. There are places to go, books to read, and movies to watch. So it’s a little unfair when he gets himself killed crossing the street.

Bob wakes up a century later to find that corpsicles have been declared to be without rights, and he is now the property of the state. He has been uploaded into computer hardware and is slated to be the controlling AI in an interstellar probe looking for habitable planets. The stakes are high: no less than the first claim to entire worlds. If he declines the honor, he’ll be switched off, and they’ll try again with someone else. If he accepts, he becomes a prime target. There are at least three other countries trying to get their own probes launched first, and they play dirty.

The safest place for Bob is in space, heading away from Earth at top speed. Or so he thinks. Because the universe is full of nasties, and trespassers make them mad – very mad.

France, 1714: in a moment of desperation, a young woman makes a Faustian bargain to live forever and is cursed to be forgotten by everyone she meets.

Thus begins the extraordinary life of Addie LaRue, and a dazzling adventure that will play out across centuries and continents, across history and art, as a young woman learns how far she will go to leave her mark on the world.
