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's the last man alive. He's then trained for the toughest conditions imaginable and placed with a crack team of specialists on an isolated island. 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 versions of our world.
