In the early twenty-first century catastrophe strikes, shattering the Earth's timelines and leaving in its wake a bleak, post-apocalyptic future. The world realigns. With past and future fractured, communities desperately cluster together for protection from marauding War Clans and predatory Scythers. Humanity is under attack from the worst enemy it's ever faced: humankind itself. In this climate of terror, a new breed of enforcer is needed--the Keepers. Ex-soldier and ex-cop, hard-drinking Keeper Jack Trevayne is armed, surly, and vulgar. Equipped with his sentient motorbike, he is the only one who can protect humanity while keeping the timelines clean. He has the skills and he has the attitude. But he'd just rather have a beer. The future is complicated--Jack is not.
