When Maddie Chambers inherits her Aunt Charlotte's gothic mansion, old memories stir of the long-forgotten summer she turned sixteen. She has barely moved in before a series of bizarre events drives her to question her sanity. The strains of her aunt's favorite song echo through the house, the roots of a faraway willow creep through the cellar, a child who cannot exist skips from room to room, and Maddie discovers Charlotte kept many deadly secrets. Gradually, the barriers in her mind fall away, and Maddie begins to recall that summer when she looked into the face of evil. Now, the long dead builder of the house has unfinished business and an ancient demon is hungry. Soon it is not only Maddie's life that is in danger, but her soul itself, as the ghosts of her past shed their cover of darkness.
