Tessa Young is a landscape architect who specializes in the design and creation of labyrinths. For years she has immersed herself in the healing aspects of these elaborate structures, searching for God and hoping to make sense of the nightmares that have plagued her since childhood. When Smith Chandler, a colleague who once betrayed her, offers an opportunity to reconstruct a remarkable Colonial-era labyrinth, she can't resist this project of a lifetime. But one evening, as dusk falls, an assailant ambushes Tessa and Smith and the real nightmare begins.
