The book guides us to discover one of the most important characters of our time: a humble and discreet woman with a lively sparkling look, that has put her life at the service of the poorest. Through powerful evocative images of his spiritual grandeur, we know about little Teresa and her childhood in Albania, her passion for music and reading, the stages of her religious education and her life as a missionary, the friendship with Pope John Paul II and Lady Diana. We follow her from the travels around the world and the everyday life among the poors in Calcutta, to the victory of the Nobel Peace Prize and the extraordinary events that led to her canonization, the most important event of the Jubilee of Mercy.
