When Kate Vavasour wakes in the hospital, she remembers nothing of the family gathered around her, or of her life before the accident. The doctors diagnose post-traumatic amnesia and say the memories should start returning. Which they do—but these memories are not hers. They belong to Isabel Vavasour, who lived and died at Askerby Hall more than 400 years earlier. Returning to Askerby Hall to recuperate, Kate finds herself in a house full of shadows and suspicions. But before she can uncover the mysteries of the present, she must first discover the truth about the past. Was Isabel's madness real, or was her mistake trusting the one person she thought would never betray her?
