Claire has absolutely no interest in the paranormal. She's a scientist, which is why she can't think of anything worse than having to help out her dad on one of his ghost-themed Chicago bus tours. She thinks she's made it through when she sees a boy with a sad face and dark eyes at the back of the bus. There's something off about his presence, especially because when she checks at the end of the tour...he's gone.

Claire tries to brush it off, she must be imagining things, letting her dad's ghost stories get the best of her. But then the scratching starts. Voices whisper to her in the dark. The number 396 appears everywhere she turns. And the boy with the dark eyes starts following her.

Claire is being haunted. The boy from the bus wants something...and Claire needs to find out what before it's too late.
