Soon Lilly and the beleaguered townspeople must join 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. But Jeremiah and his followers harbor a dark secret, the evidence of which very gradually begins to unravel. Now Lilly is caught in the dark center of a growing conflict...and it will take all of her instincts and skills to survive both the living and the dead.
