Doomsday Game — Gary Gibson

"...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

"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," Sci Fi Bulletin 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." SFF World 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." Fantasy Literature website on Book 2, Survival Game

"Gibson has certainly proved himself a name to watch." SFX on Extinction Game
