When your life is based on lies, how do you hunt down the truth? Jerry Beche should be dead. Instead, he's rescued from a desolate Earth where he was the last man alive. He's then trained for the toughest conditions imaginable and placed with a crack team of specialists. Every one of them is a survivor, as each withstood the violent ending of their own alternate Earth. And their new specialism? To retrieve weapons and data in missions to other apocalyptic worlds. But what is 'the Authority', the shadowy organization that rescued Beche and his fellow survivors? How does it access other timelines? And why does it need these instruments of death? As Jerry struggles to obey his new masters, he begins to distrust his new companions. A strange bunch, their motivations are less than clear, and accidents start plaguing their missions. Jerry suspects the Authority is feeding them lies, and team members are spying on him. As a dangerous situation spirals into catastrophe, is there anybody he can trust? A riveting, action-packed post-apocalyptic survival story from master of SF, Gary Gibson.

One civilization lies in ruins, but will they be next? Katya is a scientist, working on a top secret project for the Russian Empire. She's also desperate. Due to her classified knowledge of alternative worlds, she's being blackmailed into working as a spy - and her father's life is at stake. But Katya's assignment seems impossible. She must hunt down a mysterious artifact that could give the dying Tzar his dearest wish - new life. But it's hidden on an alternate Earth, on an American controlled island. She'll have to go deep undercover to gain access to this prize. And Borodin, the Tzar's ruthless spymaster, has his own reasons for needing the object. However, ambition blinds these men to the facts. The artifact will call down terror from the depths of space. If they use it, the Russian Empire, the Americans' beleaguered territories and all linked versions of earth face extinction. Katya discovers the truth with Jerry, an American survivalist based on the island. Together they must stop the artifact being activated, at any costs. Two civilizations depend upon it.

"...a master of core sf" - The Guardian. Rozalia is a Pathfinder, dedicated to exploring parallel Earths where mankind has been wiped out. As a survivor of one such world, she’s seen every kind of apocalypse possible. All she and her fellow Pathfinders want is a new home—both for themselves and for the organization that brought them together. Now, at last, they’ve found one: an untrammeled Eden where humanity never even evolved. But just when it looks like their work is finally over, the Pathfinders find themselves confronted by new threats. Someone has been accessing an off-limits alternate in search of weapons that could destroy them all; samples of their most advanced—and dangerous—technology have been stolen from a research facility, and toxic rain is driving people crazy—which means she might be going crazy too. Either that, or they really are being invaded from another dimension. The Pathfinders have no choice but to come together one last time and journey across Earths left lifeless by rogue singularities or littered with ancient and perilous ruins. If they don’t, an entire world dies...and millions with it. "Gibson turns the genre on its head . . . He excels at depicting real-feeling destruction and the tenacity and weaknesses of survivors, along with the moral wrestling of survivor guilt. This potent, teeth-gritting SF thriller shows death and love only a shadow away from our ordinary lives."Publishers Weekly starred review of Book 1, Extinction Game "One of the top SF writers active today . . . In the right hands, SF can be wonderful, inventive and hugely enjoyable - and Gary Gibson is just that sort of author." WalkerofWorlds.com "To be considered alongside the leading triumvirate of British hard SF writers: Alastair Reynolds, Peter Hamilton, and Neal Asher." The Guardian "A fast-paced post-apocalyptic thriller that builds to an exciting conclusion," SciFiBulletin.com on Book 1, Extinction Game "Believable characters, interesting situations, stunning settings, and, above all else, a compulsively readable story makes this a must-read for sci-fi fans. Highly recommended." SFFWorld.com on Book 1, Extinction Game "Gibson’s take on two thoroughly familiar tropes (Cold War + apocalypse) is actually quite refreshing . . . The prose is also satisfyingly good." FantasyLiterature.com on Book 2, Survival Game "Gibson has certainly proved himself a name to watch." SFX on Extinction Game
