Eleven-year-old Quinn has had some bad experiences lately. She was caught cheating in school, and then one day, her little sister, Emma, disappeared while walking home from school. She never returned.

When Quinn's best friend, Kara, has to move away, she goes on one last trip with Kara and her family. They stop over at the first hotel they see, a Victorian inn that instantly gives Quinn the creeps, and she begins to notice strange things happening around them. When Kara's parents and then brother disappear without a trace, the girls are stranded in a hotel full of strange guests, hallways that twist back in on themselves, and a particularly nasty surprise lurking beneath the floorboards. Will the girls be able to solve the mystery of what happened to Kara's family before it's too late?
