The basement of Sleepy Hollow's elementary school is haunted. At least that's what everyone says. But no one has ever gone downstairs to prove it. Until now... This year, Cassidy and Jeff's classroom is in the basement. But they're not scared. There's no such thing as ghosts, right? Tell that to the ghosts. The basement belongs to another class--a ghost class. They don't want to share. And they will haunt Cassidy and Jeff until they get their room back!
