The Walking Dead Volume 20: All Out War Part 1 (Walking Dead, 20)

* The biggest storyline in Walking Dead history starts here! It's Rick versus Negan with a little help from everyone else!
* Collects issues #115-120.
* 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 The world of commerce and frivolous necessity has been replaced by a world of survival and responsibility.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.
