Queen Elizabeth II was much more than Britain's oldest or longest-serving monarch. Admired around the world for her serenity, wisdom and unwavering devotion to duty, she was a rock of stability in turbulent, changing times.

Served by no less than 15 prime ministers, her extraordinary reign saw her visit more than 100 countries as she rubbed shoulders with powerful leaders and influential thinkers. And as Britain's empire declined, she pledged her 'heart and soul' as Head of the Commonwealth, made up of 54 richly diverse countries.

The 170 quotes inside capture the queen's personal reflections on everything from history, world affairs and the monarchy to service, sacrifice and the family. Teeming with inspirational words and pearls of royal wisdom, this book is a fitting tribute to a much cherished sovereign.
