A biography of Queen Elizabeth II and her sister Margaret examines their early idyllic youth as the closest of sisters as well as their often fraught relationship after their father's death and Elizabeth's ascension to the throne.

They were the closest of sisters until their uncle Edward Vlll decided to abdicate the throne. Then the dynamic between Elizabeth and Margaret was dramatically altered. Forever more Margaret would have to curtsy to her sister and bow to her wishes. Margaret's struggle to find a place and position inside the royal system was often a source of tension. When the Church and government would not allow her to marry a divorcé, Group Captain Peter Townsend, Margaret had to choose between keeping her title and royal allowances or her lover. Morton explores their relationship, offering unique insight into a woman resigned to duty and responsibility, and a sister resistant to it. -- adapted from jacket
