The world looks different a year after the dead rose from their graves.

Survivors live in walled enclaves while the zombies roam freely in the wasteland. John, Chris and Erik have made their home in the enclave of Haven and earn their keep in town by scavenging for supplies outside the walls. These excursions bring them face-to-face with grubby urchins, deadly warlords and hordes of the undead.

But not all threats lie beyond the walls. The dads are beginning to wonder if they can trust the people in charge. Things aren't looking good and the longer the end of the world drags on, the more danger they're sure to find themselves in.
