Politically astute, ambitious, and beautiful, Yolande of Aragon, queen of Sicily, was one of the most powerful women of the Middle Ages. Caught in the complex dynastic battle of the Hundred Years War, Yolande championed the dauphin's cause against the forces of England and Burgundy, drawing on her savvy, her statecraft, and her intimate network of spies. But the enemy seemed invincible. Just as French hopes dimmed, an astonishingly courageous young woman named Joan of Arc arrived from the farthest recesses of the kingdom, claiming she carried a divine message-a message that would change the course of history and ultimately lead to the coronation of Charles VII and the triumph of France.

Now, on the six hundredth anniversary of the birth of Joan of Arc, this fascinating book explores the relationship between these two remarkable women, and deepens our understanding of this dramatic period in history. How did an illiterate peasant girl gain access to the future king of France, earn his trust, and ultimately lead his forces into battle? Was it only the hand of God that moved Joan of Arc-or was it also Yolande of Aragon?
