Margaret Leighton wrote several other biographies of women aimed at mature young readers. These books demonstrate Leighton's exceptional ability to integrate historical background with personal detail, and in each Leighton confronts controversial issues—such as violence or drug use—with honesty and decorum. Among these titles are Judith of France, the story of Charlemagne's granddaughter, who makes two royal marriages before she finds true love; Journey for a Princess, the story of Estrid, daughter of King Alfred of England; The Story of Florence Nightingale, a sympathetic portrayal of Florence's early years; and Cleopatra: Sister of the Moon, one of Leighton's most celebrated works.
