For twenty thousand years, every observable phenomenon in the universe has been successfully explained by the Sarumpaet Rules: the laws governing the dynamics of the quantum graphs that underlie all the constituents of matter and the geometric structure of spacetime. Now Cass has stumbled on a set of quantum graphs that might comprise the fundamental particles of an entirely different kind of physics, and she has travelled three hundred and seventy light years to Mimosa Station, a remote experimental facility, in the hope of bringing this tantalising alternative to life. The “novo-vacuum” is predicted to begin decaying the instant it’s created, but even a short-lived, microscopic speck could shed light on the origins of the universe, and test the Sarumpaet Rules more rigorously than ever before. Cass’s experiment turns out to be more successful than anticipated: the novo-vacuum is more stable than the ordinary vacuum around it, and a region in which the new physics holds sway proceeds to expand out from Mimosa at half the speed of light. Six hundred years later, more than two thousand inhabited systems have been lost to the novo-vacuum. On the Rindler, a ship that has matched velocities with the encroaching border, people have come from throughout inhabited space to study the phenomenon. Most are Preservationists, hunting for a way to turn back the tide, but a few belong to another faction: Yielders, who believe that the challenge of adapting to survive on the far side of the border would reinvigorate a civilisation that has grown stale and insular. Tchicaya has come to the Rindler to join the Yielders, but when Mariama — a childhood friend whose example inspired him to abandon his own home world and traditions for a life of travel — arrives soon after, he is shocked to discover that she plans to help the Preservationists find a way to destroy the novo-vacuum. As a theoretical breakthrough leads to a sequence of experiments that begins to reveal the true richness of the world behind the border, tensions between the opposing factions grow. When a splinter group responds to these revelations with violent, unilateral action, Tchicaya and Mariama are forced into an uneasy alliance, and travel together through the border, balancing old and new loyalties against the fate of two incomparably different universes.

In 2975, the orphan Yatima is grown from a randomly mutated digital mind seed in the conceptory of Konishi polis. Yatima explores the Coalition of Polises, the network of computers where most life in the solar system now resides, and joins a friend, Inoshiro, to borrow an abandoned robot body and meet a thriving community of “fleshers” in the enclave of Atlanta. Twenty-one years later, news arrives from a lunar observatory: gravitational waves from Lac G-1, a nearby pair of neutron stars, show that the Earth is about to be bathed in a gamma-ray flash created by the stars’ collision — an event that was not expected to take place for seven million years. Yatima and Inoshiro return to Atlanta to try to warn the fleshers, but meet suspicion and disbelief. Some lives are saved, but the Earth is ravaged. In the aftermath of the disaster, the survivors resolve to discover the cause of the neutron stars’ premature collision, and they launch a thousand polises into interstellar space in search of answers. This diaspora eventually reaches a planet subtly transformed to encode a message from an older group of travellers: a greater danger than Lac G-1 is imminent, and the only escape route leads beyond the visible universe.

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.

Paul Durham keeps making Copies of himself: software simulations of his own brain and body which can be run in virtual reality, albeit seventeen times more slowly than real time. He wants them to be his guinea pigs for a set of experiments about the nature of artificial intelligence, time, and causality, but they keep changing their mind and baling out on him, shutting themselves down. Maria Deluca is an Autoverse addict; she’s unemployed and running out of money, but she can’t stop wasting her time playing around with the cellular automaton known as the Autoverse, a virtual world that follows a simple set of mathematical rules as its “laws of physics”. Paul makes Maria a very strange offer: he asks her to design a seed for an entire virtual biosphere able to exist inside the Autoverse, modelled right down to the molecular level. The job will pay well, and will allow her to indulge her obsession. There has to be a catch, though, because such a seed would be useless without a simulation of the Autoverse large enough to allow the resulting biosphere to grow and flourish — a feat far beyond the capacity of all the computers in the world.

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.

Modern technology is pitted against ancient dinosaurs in this scientific thriller James Rollins calls “Jurassic Park set amid the paradox of time travel.” Paleontologist Richard Leyster is perfectly content in his position with the Smithsonian excavating dinosaur fossil sites and publishing his findings . . . until the mysterious Harry Griffin appears in his office with a cooler containing the head of a freshly killed Stegosaurus. The enigmatic stranger offers Leyster the opportunity to travel back in time to study living dinosaurs in their original habitats—but with strings attached. Soon, the paleontologist finds himself, along with a select team of colleagues—including his chief rival, the ambitious and often ruthless Dr. Gertrude Salley—making discoveries that would prove impossible working from fossils alone. But when Leyster and his team are stranded in the Cretaceous, they must learn to survive while still keeping alive the joy of scientific discovery. This shocking novel spans hundreds of millions of years and deals with the ultimate fate not only of the dinosaurs but also of all humankind. Nominated for the Locus Award, the Hugo Award, and the Nebula Award for Best Novel, Bones of the Earth cements author Michael Swanwick as an author who “proves that sci-fi has plenty of room for wonder and literary values” (San Francisco Chronicle).

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?
