Many have called her a saint. She won the Nobel Peace Prize in 1979 and India's highest civilian honor, the Jewel of India, in 1980. Pope John Paul II declared her "Blessed," beatifying her in 2003. For nearly fifty years at the head of Calcutta's Missionaries of Charity, the Albanian-born Agnes Gonxha Bojaxhiu, better known as Mother Teresa, advocated for the poor and homeless, ministered to the sick, provided hospice for the afflicted, and embodied the very essence of humanitarianism. Now, revised and updated, Kathryn Spink's definitive, authorized biography is "simply the best . . . around," according to James Martin, SJ, author of" The Jesuit Guide to (Almost) Everything." "Thoroughly researched, sensitively written and unfailingly inspiring, Kathryn Spink's book should be, after Mother Teresa's own writings, your first resource for understanding one of the greatest saints in Christian history."
