A decade after the apocalypse started, Cyrus V. Sinclair, a mercenary for the leader of three survivor settlements, is part of a world repeating its mistakes. With most of the undead turned to dust and raiders giving up, everyone thinks they're safe behind city walls. But after a town is brutally massacred, it seems no one is safe. Well hidden, numbering in the thousands, and controlled by a new merciless leader, the crazies are stronger than ever before. When a familiar symbol keeps appearing amid the chaos, Cyrus realizes an old enemy is back. Despite the turmoil, Cyrus finally sees things clearly. He has one goal: destroy the Brotherhood or die trying.
