Scritch Scratch by Lindsay Currie is a chilling, spooky, and teeth-chattering book about a girl named Claire who loves science but has no interest in the paranormal. When her dad requests help for his ghost-themed bus tour in Chicago, she has no interest but goes either way. 

When Claire thinks everything is going well, she spots a boy with a sad face and dark eyes at the back of the bus. Something about his presence is unusual… especially because when she checks at the end of the tour, the boy disappears! Claire tries to ignore it, but that’s when the haunting begins…scratching, voices whispering, the number 396 appearing in random places. Claire believes this boy, or ghost, wants something from her, she needs to find out, before it’s too late.
