No one knows what caused the dead to rise. No one knows what caused them to attack the living. Fighting for their lives, scattered survivors find the attempted cure to be almost worse than the disease. In the twilight of a shattered civilization, the fate of humankind rests upon the actions of a handful of war-weary survivors. Driven to a scorched corner of the former United States, they alone hold the key to a global reawakening. Or the final epitaph for a dead planet.
