Catherine of Siena was a particular favorite of Undset, who also was a Third Order Dominican. An extraordinarily active, intelligent, and courageous woman, Catherine at an early age devoted herself to the love of God. The intensity of her prayer, sacrifice, and service to the poor won her a reputation for holiness and wisdom, and she was called upon to make peace between warring nobles. 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.
With sensitivity to the zealous love of God and man that permeated the life of Saint Catherine, Undset presents a most moving and memorable portrait of one of the greatest women of all time.
