Mara is a Japanese-American girl with a history of personal tragedy. Though she still cuts to quell the pain, she thought she had left the worst behind her. But her boyfriend's sudden death and a visit to one of the most haunted places in Washington State send her into a spiral of madness that lands her in a psychiatric ward. Already suffering from dreams of a strange, ghost-infested house in the woods, Mara begins to question the very existence of reality. She is forced to confront the truth of her older sister's brutal murder and, unable to distinguish between nightmare and waking any longer, the reason the ghosts have chosen her as their conduit.
