“Eight o'clock, Portgrave Pier. Can you keep secrets? - that's what they wrote to her. Early last week, a pristine white envelope landed on her doormat. Inside was a photograph that no one but Ava had ever seen. And I shouldn't have seen it. Someone used an old typewriter and typed today's date and cryptic instructions on the back. And nothing more. It was like blackmail. Why else would anyone send Ava this photo? This letter forces sixteen-year-old Ava to come to an island with an abandoned amusement park. She is one of ten teenagers, each harboring a dark secret. When the fog engulfs the pier, the group finds itself cut off from the mainland. What lengths will the heroes go to in order not to reveal their secrets and... survive this night?
