Despite living in Key West his whole life, 18-year-old Liam Breyer is a skeptic of the supernatural until a vengeful spirit, murdered fifty years ago, nearly drowns him in a swimming pool. Luckily help arrives in the form of pretty - albeit homesick - ghost whisperer Autumn Abernathy, whose newly-divorced mom has dragged her to the island to live and work at the Cayo Hueso, a haunted bed and breakfast. Although they initially mistrust each other, Autumn and Liam team up to solve the decades-old mystery. But on an island where every third resident is a ghost, dealing with an unstable spirit has deadly consequences. If Liam and Autumn don't unmask the killer soon, they're likely to become Key West's latest haunted attraction.
