In the harrowing conclusion of this post-apocalyptic saga, the world is on the brink of total collapse, and the undead are closing in from every side.
After being separated from her family, Margaret—along with her new companion—must navigate their way through the overrun capital. Along their journey, they encounter a specialized military unit with their own unique mission. Forced to join forces, she and the soldiers must survive wave after wave of the undead in order to complete their mission and return Margaret to her family.
Meanwhile, Margaret's family attempts to deal with her loss while desperately trying to establish a safe haven in the heart of the Lake of the Ozarks. But as they carve out a place of refuge, they stumble upon a small, beleaguered group of survivors under relentless assault by a massive horde of undead. Banding together, Scott, Emma, and the survivors must face impossible odds to protect what little remains of the world they once knew.
Will they find each other in time, or will the darkness of this new world tear them apart forever?
