Natalie Byron had a happy life in Glasgow. She had a steady job, supportive friends and a loving family. Or at least, she thought she did. The morning after a date, Natalie wakes up inside a strange house, in a strange bed, sleeping next to a man named Jamie who claims he is her boyfriend. Outside the window are rugged cliffs surrounded by endless sea. All her things are here. The clothes in the drawer are hers and so are the bottles of shampoo in the bathroom. But this isn't her life and Jamie certainly isn't her boyfriend. Fearing she's been kidnapped, Natalie flees, but not one person on the island will help her. When everyone around her insists that her life in Glasgow is nothing but a delusion, Natalie begins to doubt her own sanity. But there is one thing Natalie is sure of. She needs to get off this island.
