The Queen by Andrew Morton

Only 25 when she became queen after the premature death of her father, Queen Elizabeth has become the stuff of superlatives. But her sovereignty has not been without personal anguish and controversy. Divorce - and the fallout from it - has shaped her reign. Her private life has been molded by an irascible husband, an extravagant mother, a querulous heir, and a shamed second son. She has refereed a war between two of her grandsons, William and Harry, once inseparable friends.
