Tom Walker just wanted a quiet getaway. But the lake has secrets. Dark ones. And now an innocent girl has gone missing . . . The police haven't had any luck finding twelve-year-old Amy Turnberry in the small lake town of Soddy Daisy, Tennessee. Walker, being the stranger, is an easy target for suspicion. What they don't understand is that he's also their only chance against what is coming. When Walker decides he has no choice but to help, not even his long career of hunting bad guys can prepare him for the evil working in the shadows. What at first seems like a small-time kidnapping, quickly evolves into a sinister crime ring, whose motives reach beyond the physical realm. Walker discovers that he only has one shot at saving Amy; the night of the full moon. Somewhere near the water. And he'll have to risk it all before Amy unwillingly becomes the ultimate sacrifice.
