The town of Woodbury is gradually recovering from the tyrannical rule of its insane leader, turning into a real oasis of safety among the plague of the walking dead. Lilly Cole and a small group of survivors are determined to overcome the traumas of their past... even as they face a new challenge very soon: an unprecedented herd of zombies, driven by an insatiable hunger, is very close at hand. The goal of the walkers is Woodbury.

But things - especially in the reality of the walking dead - are often not what they seem, and the familiar world can turn upside down in a matter of moments...
