Catherine has been studying and teaching about Leonardo da Vinci for more than a decade. She loves sharing him with students of all ages. Her first book on him, "Da Vinci: His Life and His Legacy," was a short, but still complete, family-friendly biography of his life. Over the last several years she has started a series of historically based novels about Leonardo, that currently includes "Leonardo the Florentine," "Leonardo: Masterpieces in Milan," "Leonardo: To Mantua and Beyond," and "Leonardo: A Return to Rome." Each of these novels have been well-researched, and give a fascinating view of both Leonardo da Vinci and the time and place he lived and worked.
