Life has been reduced to survival as civilization collapses under a mysterious force turning people into rage-fueled killing machines and the walking dead. Former Marine, Jack Williams, is making his way to the mountains when a strange little girl, Thalia, and her cat cross his path. In their fight for survival, Jack finds that more in the world has changed than just the undead as Thalia grows into a power that even she doesn't understand. In their fight for survival, Jack struggles with his own demons brought home from the war as they face off with a threat far more dangerous than the living dead.
