After hearing voices among an eerie copse of trees in the woods, 17-year-old Curtis must confront his worst fear: that he has inherited his father's mental illness. A desperate search for answers leads him to the discovery of Gravenhearst, a cursed mansion that burned down in 1894. When he glimpses a desperate girl in his bedroom mirror, he's sure she's one of the fire's victims. If he can unravel the mystery, he can save his sanity . . . and possibly the mysterious girl he grows to love. But more than 100 years in the past, the girl in the mirror is fighting her own battles. When her mother disappears and her lecherous stepfather reveals his true intensions, she and her sister fight to escape the evil Gravenhearst-before the estate devours them both.
