The world we knew is gone. The world of commerce and frivolous necessity has been replaced by a world of survival and responsibility. An epidemic of apocalyptic proportions has swept the globe, causing the dead to rise and feed on the living. In a matter of months society has crumbled: no government, no grocery stores, no mail delivery, no cable TV. In a world ruled by the dead, the survivors are forced to finally start living.

In the last volume we learned that no one is safe. Now, after the staggering losses they've sustained, Rick and Carl are left to pick up the pieces and carry on, knowing that they could join their fallen friends and family at any moment.
