Mark Stine’s vacation on an island resort is turning into a nightmare. He’s chased by the ghost of a medieval monk, Abbot Thomas, and fear consumes the island when the body of a retired teacher is found in a grave by the beach. As bodies pile up, the Follower, a shadow doing the Abbot’s killing, becomes more active. Mark needs to solve the White Tower’s mystery, or he might become a ghost himself.
