Nemo’s mother and father left him behind to enter “the Bin”–joining twelve billion uploaded personalities who live in crime-free, disease-free and deathless virtual societies.

Nemo has come of age on a dangerous, near-deserted planet populated by a handful of stragglers: religious fundamentalists and rebels, the creeps and the crazies. Now he is twenty-one. And on a rare, reluctant visit to the parents who abandoned their flesh and blood son for cyber-utopia, Nemo has met the perfect woman: a new Bin arrival named Justine, a beautiful pop singer who dreams other people’s dreams in the virtual night.

Now an inconvenient attraction is leading two lovers into a perilous mire of irreversible choice. For Justine has no body to return to. And Nemo the renegade has sworn never to sacrifice his own; to live, age, and die instead in a bleak earthly hell. Because, as an outsider, he may enter the Bin for short periods of time. But if he ever decides to stay…there will be no way out again.

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.

In AD 2600 the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature’s boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems. And throughout inhabited space the Confederation Navy keeps the peace. A true golden age is within our grasp.

But now something has gone catastrophically wrong. On a primitive colony planet a renegade criminal’s chance encounter with an utterly alien entity unleashes the most primal of all our fears. An extinct race which inhabited the galaxy aeons ago called it “The Reality Dysfunction.” It is the nightmare which has prowled beside us since the beginning of history.

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.

Diplomat Byr Genar-Hofoen has been selected by the Culture to undertake a delicate and dangerous mission. The Department of Special Circumstances—the Culture’s espionage and dirty tricks section—has sent him off to investigate a 2,500-year-old mystery: the sudden disappearance of a star fifty times older than the universe itself. But in seeking the secret of the lost sun, Byr risks losing himself.

There is only one way to break the silence of millennia: steal the soul of the long-dead starship captain who first encountered the star, and convince her to be reborn. And in accepting this mission, Byr will be swept into a vast conspiracy that could lead the universe into an age of peace . . . or to the brink of annihilation.

On a remote, icy planet, the soldier known as Breq is drawing closer to completing her quest.

Once, she was the Justice of Toren – a colossal starship with an artificial intelligence linking thousands of soldiers in the service of the Radch, the empire that conquered the galaxy.

Now, an act of treachery has ripped it all away, leaving her with one fragile human body, unanswered questions, and a burning desire for vengeance.

2057. Bella Lind and the crew of her nuclear-powered ship, the Rockhopper, push ice. They mine comets. But when Janus, one of Saturn’s ice moons, inexplicably leaves its natural orbit and heads out of the solar system at high speed, Bella is ordered to shadow it for the few vital days before it falls forever out of reach.

In accepting this mission she sets her ship and her crew on a collision course with destiny—for Janus has many surprises in store, and not all of them are welcome…
