The Dissociative Identity Disorder Sourcebook - Deborah Haddock Bray

Finally, a book that addresses your concerns about DID

From Eve to Sybil to Truddi Chase, the media have long chronicled the lives of people with dissociative identity disorder (DID), formerly known as multiple personality disorder. The Dissociative Identity Disorder Sourcebook serves as a much-needed bridge for communication between the dissociative individual and therapists, family, and friends who also have to learn to deal with the effects of this truly astonishing disorder.
