A girl calling herself Jane Anonymous shares her story--the story of how she was kidnapped and held in a room--with nothing but a bed, refrigerator, and adjoining bathroom--for seven months. She only saw her captor when he dragged her into the room from the trunk of his car, but she did make contact with Mason, one of the other kidnapped teens, and together they made plans to escape. When the day comes, however, Jane has to leave Mason behind or risk getting caught herself. Now, though, the cops do not believe there were any other kidnapped teens. Jane determines to write her story for herself and find Mason at all costs.
