Sybil: The True Story of a Woman Possessed by Sixteen Separate Personalities 
A controversial cult classic, Sybil by Flora Rheta Schreiber is the extraordinary story of a woman who suffered from multiple personality disorder. 'How are you today?' the doctor asked. 'I'm fine', was the reply. 'But Sybil isn't. She was so sick she couldn't come. So I came instead.' A collaboration between journalist Flora Rheta Schreiber and Sybil's psychiatrist, Dr. Cornelia Wilbur, Sybil is the story of a woman with sixteen separate personalities, and was instrumental in influencing the definition and diagnosis of multiple personality disorder. Sybil's diagnosis has since been called into question - but, forty years after it was first published, her story remains a gripping and disturbing account of one woman's struggle for mental stability and happiness.
