Rot & Ruin is a science fiction novel written by Jonathan Maberry and published by Simon & Schuster, set in the post-zombie apocalypse. Rot & Ruin takes place fourteen years after the zombie outbreak, when most living humans are spread out in small settlements just barely getting by. The communities rely on traders who pass through and the sparse gardens that a few people cultivate. Rot & Ruin plays out in a settlement and in the land outside of the fence, the Rot and Ruin. The Rot and Ruin is the dangerous land where zombies live.
