"This is a teeth-chattering, eyes bulging, shuddering-and-shaking, chills-at-the-back-of-your-neck ghost story. I loved it!"—R.L. Stine, author of the Goosebumps series For fans of Small Spaces and the Goosebumps series by R.L Stine comes a chilling ghost story based on real Chicago history about a malevolent spirit, an unlucky girl, and a haunting mystery that will tie the two together. 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 is being haunted. The boy from the bus wants something...and Claire needs to find out what before it's too late.
