Out of the ashes of its dark past, Woodbury, Georgia, becomes an oasis of safety amidst the plague of the walking dead - a town reborn in the wake of its former tyrannical leader, Philip Blake, aka The Governor.
Blake's legacy of madness haunts every nook and cranny of this little walled community, but Lilly Caul and a small ragtag band of survivors are determined to overcome their traumatic past... despite the fact that a super-herd is closing in on them.
This vast stampede of zombies, driven by inexorable hunger and aimed directly at Woodbury, becomes their first true test. But Lilly and company refuse to succumb, and in a stunning counteroffensive, the beleaguered townspeople save themselves by joining forces with a mysterious religious sect fresh from the wilderness.
Led by an enigmatic preacher named Jeremiah, this rogue church group seems tailor made for Woodbury and Lilly's dream of a democratic, family-friendly future. The two factions meld into one, the town prospers, and everything seems hopeful for the first time since the plague broke out.
But things - especially in the world of the walking dead - are often not what they seem. Jeremiah and his followers harbor a dark secret, the evidence of which very gradually begins to unravel.
