Growing up with an unstable, often absent father who preached about the end of the world, Jenna never thought in her wildest nightmares that his predictions would come true.

The mysterious ex-marine named Mason owes a life-debt to Jenna's father. Skilled and steadfast, he's ready for the prophesied Change, but Jenna proves tough to convince: until the power grid collapses and mutant dogs attack.
