For nineteen-year-old Harriet Morton, life in 1912 Cambridge is as dry and dull as a biscuit. Her stuffy father and her opressive aunt Louisa allow her only one outlet: ballet. When a Russian ballet master comes to class searching for dancers to fill the corps of his ballet company before their South American tour, Harriet's world changes. Defying her father's wishes and narrowly escaping the clutches of the man who wishes to marry her, Harriet sneaks off to join the ballet on their journey to the Amazon. There, in the wild, lush jungle, they perform Swan Lake in grand opera houses for the wealthy and culture-deprived rubber barons, and Harriet meets Rom Verney, the handsome and mysterious British exile who owns the most ornate opera house. Utterly enchanted by both the exotic surroundings and by Rom's affections, Harriet is swept away by her new life, completely unaware that her father and would-be finacé have begun to track her down. . . .
