A memoir by a young woman who spent thirteen years as Jackie Kennedy's personal assistant and occasional nanny, and the lessons about life and love she learned from the glamorous first lady. In 1964, Kathy McKeon was nineteen years old and newly arrived from Ireland when she was hired as the personal assistant to former first lady Jackie Kennedy. The next thirteen years of her life were spent in Jackie's service, during which Kathy not only played a crucial role in raising young Caroline and John Jr., but also had a front-row seat to some of the twentieth century's most significant events. Although Kathy called Jackie "Madam," she considered her employer more like a big sister who, in many ways, mentored her on how to be a lady. Kathy was there during Jackie and Aristotle Onassis's courtship and marriage and Robert Kennedy's assassination, dutifully supporting Jackie and the children during these tumultuous times in history.
