Bestselling biographer and royal commentator Robert Hardman has had unique access to the world of Elizabeth II - including family, staff, advisors and even the last state visitor of her record-breaking reign, President Donald Trump himself - to produce this intimate, authoritative, richly entertaining new portrait of the late Queen in her centenary year.

As daughter, wife, mother and Sovereign, Elizabeth II lived fascinating parallel lives, both in private and in public. But she remained something of a mystery - beloved, even revered, modest yet daunting, naturally shy but globally recognizable, inscrutable and also authentic. She was grand but so familiar that we felt we knew her. Yet we would always be left asking the same question: 'What's she really like?' No one has written more authoritatively on Elizabeth II than Robert Hardman. Who better to answer that question?

The only biographer to have interviewed all the senior members of the Royal Family, some of them several times, Hardman has crafted a gripping story of drama, devotion, triumph, tragedy, humour and conflict; of an outwardly stoical, inwardly complex woman whose love of family, love of country and duty to the Crown might pull her in different directions but never derailed her; a global stateswoman who wielded her great authority with charm and understatement.

Elizabeth II will explain why she was not merely the most famous woman in the world. She was one of history's all-time greats.

'If you read one biography on Elizabeth II, this is the one . . . magnificent' - Simon Sebag Montefiore, author of The World: A Family History of Humanity
