Sikkim, a tiny Buddhist kingdom sandwiched between India and China, survived the withdrawal of the British Empire and the Chinese invasion of Tibet. Then, in 1975, it was quietly annexed by India, bringing its 300-year-old dynasty to an end. Drawing on interviews and archive material, and retracing a 1922 journey by the author's grandfather, this book tells the remarkable story of this forgotten Shangri-La, its last king and his American wife, and the global power struggles that spelled its doom.
