After the extinction of humans, how do you define humanity?

Since the Introdus in the twenty-first century, humanity has reconfigured itself drastically. Most chose immortality, joining the polises to become conscious software. Others opted for gleisners: disposable, renewable robotic bodies that remain in contact with the physical world of force and friction. Many of these have left the solar system forever in fusion-drive starships. And there are the holdouts: the fleshers left behind in the muck and jungle of Earth-some devolved into dream apes, others cavorting in the seas or the air-while the statics and bridgers try to shape out a roughly human destiny. But the complacency of the citizens is shattered when an unforeseen disaster ravages the fleshers and reveals the possibility that the polises themselves might be at risk from bizarre astrophysical processes that seem to violate fundamental laws of nature. The orphan Yatima, a digital being grown from a mind seed, joins a group of citizens and flesher refugees in a search for the knowledge that will guarantee their safety-a search that puts them on the trail of the ancient and elusive Transmuters, who have the power to reshape subatomic particles, and to cross into the macrocosmos, where the universe we know is nothing but a speck in the higher-dimensional vacuum.

Nasim is a young computer scientist, hoping to work on the Human Connectome Project: a plan to map every neural connection in the human brain. But funding for the project is cancelled, and Nasim ends up devoting her career to Zendegi, a computerised virtual world used by millions of people.Fifteen years later, a revived Connectome Project has published a map of the brain. Zendegi is facing fierce competition from its rivals, and Nasim decides to exploit the map to fill the virtual world with better Proxies: the bit-players that bring its crowd scenes to life. As controversy rages over the nature and rights of the Proxies, a friend with terminal cancer begs Nasim to make a Proxy of him, so some part of him will survive to help raise his orphaned son. But Zendegi is about to become a battlefield ...

Collected together here for the first time are twelve stories by the incomparable Greg Egan, one of the most exciting writers of science fiction working today.In these dozen glimpses into the future Egan continues to explore the essence of what it is to be human, and the nature of what - and who - we are, in stories that range from parables of contemporary human conflict and ambition to far-future tales of our immortal descendants.Return to the universe of the meta-civilisation known as the Amalgam, which Egan explored in his critically acclaimed novel Incandescence: ''Riding the Crocodile'', which recounts an epic endeavour a million years from now to bridge the divide between the Amalgam and the reclusive Aloof; ''Glory'', set in the same future, in which two archaeologists strive to decipher the artefacts of an ancient civilisation, and ''Hot Rock'', where an obscure, sunless world conceals mind-spinning technological marvels, bitter factional struggles, and a many-layered secret history.This superb collection also includes the title story, the Hugo Award-winning ''Oceanic'': a boy is inducted into a religion that becomes the centre of his life, but as an adult he must face evidence that casts a new light on his faith.

A million years from now, the galaxy is divided between the vast, cooperative meta-civilisation known as the Amalgam, and the silent occupiers of the galactic core known as the Aloof. The Aloof have long rejected all attempts by the Amalgam to enter their territory, but have permitted travellers to take a perilous ride as unencrypted data in their communications network, providing a short-cut across the galaxy''s central bulge.When Rakesh encounters a traveller, Lahl, who claims she was woken by the Aloof on such a journey and shown a meteor full of traces of DNA, he accepts her challenge to try to find the uncharted world deep in the Aloof''s territory from which the meteor originated.Roi and Zak live inside the Splinter, a world of rock that swims in a sea of light they call the Incandescence. Living on the margins of a rigidly organised society, they seek to decipher the subtle clues that can reveal the true nature of the Splinter. In fact, the Splinter is orbiting a black hole, which is about to capture a neighbouring star, wreaking havoc. As the signs of danger grow, Roi, Zak, and a growing band of recruits struggle to understand and take control of their fate. Meanwhile, Rakesh is gradually uncovering their remote history, and his search for the lost DNA world ultimately leads him to a civilisation trapped in cultural stagnation, and startling revelations about the true nature and motives of the Aloof.

In Yalda''s universe, light has mass, no universal speed, and its creation generates energy; on Yalda''s world, plants make food by emitting light into the dark night sky. And time is different: an astronaut might measure decades passing while visiting another star, only to return and find that just weeks have elapsed for her friends.

On the farm where she lives, Yalda sees strange meteors that are entering the planetary system at an immense, unprecedented speed - and it soon becomes apparent that more of this ultra-fast material is appearing all the time, putting her world in terrible danger. An entire galaxy is about to collide with their own.

There is one hope: a fleet sent straight towards the approaching galaxy, as fast as possible. Though it will feel like weeks back home, on board, millennia will pass before the collision, time enough to raise new generations, and time enough to find a way to stop the ultra-fast material.

Either way, they have a chance to save everyone back on the home world.

THE HUNDRED LIGHT YEAR DIARY - Scientists can bounce messages from the future back to the present, but there''s no guarantee they''ll tell the truth ...

LEARNING TO BE ME - Crystalline minds may take the place of human brains, but where does the self really lie?

CLOSER - Lovers exchange bodies and minds, but their experiments go just that little bit too far, proving that you can have too much of a good thing

It''s late in the 21st century and bioengineering is now so common that people are able to modify their minds in any way they wish. It is an era which has been shaped by information systems so vast that security, in any form, is easily breached. Now you can be whatever you want to be, and do whatever you want to do. On Earth anyway. One night, thirty three years ago, the stars went out. ''The Bubble'' - a perfect sphere centred on the sun - appeared in the sky, isolating the solar system from the rest of the universe. For thirty-three years, humanity has lived with the religious cults and terrorism which spawned in the wake of the darkness.We are now alone. Humanity has been cut off. Quarantined.

On the utopian, man-made island, Stateless, Nobel Prize winner Violet Mosala is close to solving the greatest problem of her career - the quest for the ultimate Theory of Everything (TOE) is almost over.Burned out by recording the abuses of biotech for his TV news syndicate, Andrew Worth grabs the chance to follow Violet''s story. In contrast the world of theoretical physics seems like an anaesthetised mathematical heaven, where everything is cool and abstract. He could not have been more wrong. One by one Mosala''s rival quantum physicists are disappearing from the scientific summit at Stateless. But why? Is it something to do with Violet herself, or is there some other, more esoteric, force at work undermining the Theory of Everything Conference?

As a young boy, Prabir Suresh lives with his parents and sister on an otherwise uninhabited island in a remote part of the Indonesian peninsula. Prabir names it Teranesia, populating it with imaginary creatures even stranger than the evolutionarily puzzling butterflies that his parents are studying. Civil war strikes, orphaning Prabir and his sister. Eighteen years later, rumours of bizarre new species of plants and animals being discovered in the peninsula that was their childhood home draw Prabir''s sister back to the island - Prabir cannot bear for her to have gone out alone and he follows, persuading a pharmaceutical researcher to take him along as a guide.

Cass has stumbled on something that might be an entirely different type of physics, and she''s travelled three hundred and fifty light-years to Mimosa Station, a remote experimental facility, to test her theory. The novo-vacuum she creates is predicted to begin decaying the instant it''s created, but even so short-lived a microscopic speck could shed new light on the origins of the universe.But instead of decaying, Cass''s novo-vacuum is wildly successful and begins expanding, slowly but inexorably taking over the universe ...SCHILD''S LADDER: a wild ride through the far future by one of the world''s most respected and acclaimed writers.

The generation ship Peerless is suffering from a population explosion, and the only way to reduce the number of children is by drastically limiting the females'' food intake. So population control consists of two barbaric choices: starvation, or suicide.Trying to find a better way, a biologist starts experimenting with animals, and stumbles on a technique that radically alters the reproductive cycle. But while the advantages are obvious, there''s a major drawback: while it spares women from their old role - reproduction without hope of survival - it will essentially wipe out an entire sex.Amid the turmoil created by this new possibility, physicists on the ship are working to develop the technology they will need to complete the mission of the Peerless. One of the expedition''s founders dreamed of discovering the Eternal Flame: a way to generate thrust without consuming any fuel at all.The inhabitants on board the Peerless have some hard choices to make - and the wrong one could spell extinction for their entire race.

In an alien universe where space and time play by different rules, interstellar voyages last longer for the travellers than for those they left behind. After six generations in flight, the inhabitants of the mountain-sized spacecraft the Peerless have used their borrowed time to develop advanced technology that could save their home world from annihilation.But not every traveller feels allegiance to a world they have never seen, and as tensions mount over the risks of turning the ship around and starting the long voyage home, a new complication arises: the prospect of constructing a messaging system that will give the Peerless news of its own future.While some of the crew welcome the opportunity to be warned of impending dangers - and perhaps even hear reports of the ship''s triumphant return - others are convinced that knowing what lies ahead will be oppressive, and that the system will be abused. Agata longs for a chance to hear a message from the ancestors back on the home world, proving that the sacrifices of the travellers have not been in vain, but her most outspoken rival, Ramiro, fears that the system will undermine every decision the travellers make.When a vote fails to settle the matter and dissent erupts into violence, Ramiro, Agata and their allies must seek a new way to bring peace to the Peerless - by traveling to a world where time runs in reverse.THE ARROWS OF TIME is the final volume of the Orthogonal trilogy, bringing a powerful and surprising conclusion to the epic story of the Peerless that began with THE CLOCKWORK ROCKET and THE ETERNAL FLAME.
