In 1984, seventeen-year-old Rose and her fiancé discover an injured girl with no memory. The girl, Jordan, is in Rose’s life for a brief time but leaves her world shattered.
Years later, Rose Crosby’s fifteen-year-old daughter Ginny can’t understand why her relationship with her mother has fallen apart. Ginny could swear that Rose is terrified of her lately.
Then one terrible day, Ginny overhears Rose confessing that she truly is terrified of Ginny—because to her, every day Ginny grows more and more like Jordan, the girl who's been dead many years. In fact, she swears that somehow, Ginny is turning into Jordan.
Is Ginny’s mom insane? Is there a ghost in their house, threatening to possess Ginny? Or is the demon in Rose's past, forcing her to confront what happened on that horrible day in 1984 when Jordan was killed?
