Maria has never gotten over her sister Isabella's death...and the guilt she feels about what happened. It hangs over everything she does, even an innocent slumber party with her two best friends. When one friend suggests they play a game that summons the spirits of the dead, Maria thinks it's all make-believe. But then she starts to hear from a spirit — a spirit claiming to be her sister. Maria doesn't want to think it's possible...but the sinister spirit has a way of making her listen. Has her sister actually returned?
