Lauren has a disorder that makes her believe everything her friends tell her―and she believes everyone is her friend. Her innocence puts her at constant risk, so when she gets the opportunity to have an operation to correct her condition, she seizes it. But after the surgery, Lauren is changed. Is she a paranoid lunatic with violent tendencies? Or a clear-eyed observer of the world who does what needs to be done? Told in journal entries and therapy session transcripts, the book is a collection of Lauren's papers, annotated by her sister long after the events.
