By talking to new sources speaking publicly about Marilyn for the first time, acclaimed biographer J. Randy Taraborrelli draws sympathetic portraits of the women so influential in the actress' life, including her mentally ill mother, her foster mother, her legal guardian and her half-sister. He gives insights into her love affairs with Sinatra, DiMaggio and Miller and new information on her relationships with the Kennedys - Bobby, Jack and Pat. He examines what evidence really exists on the many theories published about this time in her life - and comes to a conclusion that will surprise many. He also reveals, for the first time, the shocking scope of Marilyn's own mental illness, and the lonely battle she fought with her own mind.
