The Kennedy family has long held the world's admiration and fascination. But all families have their dark secrets and for the Kennedys it was the daughter born with developmental disabilities, Rosemary. At age 23, her Father subjected her to an experimental lobotomy for fear that if her limitations were discovered, it would reflect badly on his successful sons. She would spend the next 60 years in an institution. "Rosemary: The Hidden Kennedy Daughter," by Kate Clifford Larson tells the heartbreaking account of a daughter who knew her mere existence disappointed her father. She is the first biographer to have access to all of Rosemary's known letters.
