Mary has always been different. Shed like to be normal, but being able to hear ghosts means shell never be like everyone else. She starts her junior year of high school hoping to be left alone, but Cyrus Asher is new and doesnt know or seem to care that shes an outcast. They start hanging out and all is well until she goes over to his house. Cys house is haunted, and not by Caspar, the friendly ghost. But its not the ghost that ruins the evening. That honor belongs to Vicky The Hickey Nelson with her borrowed Ouija board and stuck-up friends. They make Mary so angry that she uses the ghost to freak out everybody, Cy included. He orders her out, and Mary thinks shes lost whatever chance she had with him. But theres still the ghost to deal with. Hes mean, nasty, and possibly homicidal.
