In a tiny Arkansas town, fourteen-year-old Mary Lanham lives an unremarkable life until the day a man in a long, gray cloak creeps out of the forest, and a centuries-old mystery begins to unfold. Her elderly father is hiding an artifact of great power, and dangerous people have come to town looking for it. Suddenly, Mary's ordinary and rather boring life is turned upside down. As the danger grows, Mary learns the secrets of her past and discovers her true destiny, a destiny that will change everything for her, for her friends, and for their tiny hometown.
