In 1912, twenty-year-old Tilly Harper leaves the peace and beauty of her native Lake District for London, to become assistant housemother at Mr. Shaw’s Home for Watercress and Flower Girls. For years, the home has cared for London’s flower girls—orphaned and crippled children living on the grimy streets and selling posies of violets and watercress to survive.
Soon after she arrives, Tilly discovers a diary written by an orphan named Florrie—a young Irish flower girl who died of a broken heart after she and her sister, Rosie, were separated. Moved by Florrie’s pain and all she endured in her brief life, Tilly sets out to discover what happened to Rosie. But the search will not be easy. Full of twists and surprises, it leads the caring and determined young woman into unexpected places, including the depths of her own heart.
