During her 1890 trip to the United States, Mother Cabrini began the custom of writing letters to her sisters in the form of a travel diary. These letters appear here in chronological order in a new English translation. They show an intimate side of the saint that a biography is unable to reveal. Not many women of her time traveled as extensively as Frances Cabrini, with such an interest and passion to learn about her shipmates on board as well as the people and the land of the countries she passed. She described all this for the sisters of that time who eagerly awaited and circulated her letters. The material they contain is of lasting interest.
