Four years have passed and Cassie Belanger is plagued with nightmares, ghostly voices from the past, and a compulsion to return to the sleepy fishing town of Oysterville, Washington. There, she meets two strangers who have followed the same mysterious obsession. Cassie and her new friends must race against time to solve the mysteries of cryptic letters, terrifying dreams, and a shadowy figure bent on finding a long forgotten treasure before they do, and more than willing to murder anyone in his way. Danger, mystery, love, and fortune await Cassie as she finds her way back to Oysterville once more.
