Kathy just wanted a quiet summer. After teaching twenty-seven children, she was tired, so she rented a beach house on a sparsely populated island. She loved it there. But after a couple of weeks she was awakened nightly by strange noises and lights. They were coming from a natural cove close to her rental house. Nightly they worsened; no one seemed to notice but her. Before that, she was attacked by a mongrel dog and that was when she met Toby and his dad, Zac. Zac preached on Sundays in the church on the island. Church was not something with which Kathy was familiar. Later Mrs. Wilson, the local storekeeper's wife, disappeared. Shortly thereafter, a stolen necklace was found by Kathy on the beach close to her house, and the next day she found a body. Someone wanted Kathy dead. These people were her friends, or were they?
