Too Small a World is the bestselling biography of Mother Francesca Cabrini (1850-1917), an Italian-American religious sister who founded the Missionary Sisters of the Sacred Heart of Jesus, a Catholic religious institute, which became a major support to the Italian immigrants to the United States in the 19th century. Sister Cabrini was also the first naturalized citizen of the United States to be canonized by the Roman Catholic Church in 1946. Born in Northern Italy in 1850, Sister Cabrini was a woman of great compassion and courage. Inspired by her deep faith in Jesus Christ, she saw her life as a mission to relieve suffering and serve those in need-in particular the poor and excluded. Sister Cabrini established health, education and care centres in the U.S.A. and Latin America, Europe and England, becoming an inspiration to all those whose lives she touched.
