In Catherine of Siena, Sigrid Undset paints a portrait of a fourteenth century saint, one of the most courageous women of all time. With sensitivity to the zealous love of God and man that permeated the life of Saint Catherine, Undset tells the story of how prayer, sacrifice, and service to the poor won her a reputation for holiness and wisdom. Called upon to make peace between warring nobles and believing that peace in Italy could be achieved only if the Pope, then living in France, returned to Rome, Catherine boldly traveled to Avignon to meet with Pope Gregory XI.
