Tessa Young, an up-and-coming landscape architect who specializes in the design and creation of labyrinths, has immersed herself in the mythological, spiritual, and healing aspects of the elaborate structures. She also is searching for God and hoping to make sense of the nightmares that have plagued her since childhood. When Smith Chandler, an estranged colleague--with whom she'd half fallen in love a dozen times before catching herself every time--calls to propose a project he claims is the opportunity of a lifetime, she reluctantly agrees to check it out. Smith is reconstructing a pre-Revolutionary War abbey for wealthy clients. Among its remarkable features is an overgrown labyrinth. Unable to resist, Tessa accepts his offer to work with him. Soon she is immersed in the project of a lifetime. But one evening, after weeks of work in the labyrinth, Tessa and Smith are attacked. While protecting Tessa, Smith is stabbed, and the nightmare begins...again.
