"Queen of the World has a vivid international tenor that separates it from the long shelf of previous Elizabeth II biographies. The result of this new Commonwealth approach is that rarest of rarities: a Queen Elizabeth II book that’s actually different from all the other Queen Elizabeth II books. In 2019 that’s feat enough; that the book should also be so consistently entertaining is something of a royal bonus."

– Open Letters Review

"Hardman’s book, filled with new details, will be an essential source for any historian of modern Britain. It’s also a glorious read."

– The Spectator (UK)

"An intimate portrait of the Royal commitments at home and abroad. Provides an exceptional insight into the work of the Queen and other members of the Royal Family."

– BBC Entertainment

"Hardman insightfully addresses [the Queen’s] royal tours, state visits of foreign leaders to London, her leadership in the evolution of her position as head of the Commonwealth, her participation in the special relationship with the U.S., and the role of the royal yacht, Britannia, in spreading the goodwill of the queen globally. Throughout, Hardman's analysis is discerning, knowledgeable, and fascinating."

– Booklist (starred)

"A portrait of Queen Elizabeth II that highlights her many accomplishments. The book is grounded in lucid historical detail and often highlighted by colorful anecdotes. A respectful and thoughtfully documented history of the British monarch."
