The first in-depth dual-biography of Elizabeth & Margaret, written by the bestselling royal biographer, Andrew Morton. They were the closest of sisters and the best of friends. But when, in a quixotic twist of fate, their uncle Edward VIII decided to abdicate the throne, the dynamic between Elizabeth and Margaret was dramatically altered. From the idyll of their cloistered early life, through their hidden wartime lives, into the divergent paths they took following their father's death and Elizabeth's ascension to the throne, this book explores their relationship over the years.
