This is the story of three orphan immigrants – Maria, an Italian in her early teens, Molly, a little Irish girl with a way of getting into trouble, and Ming, a very shy Chinese girl. Maria, Molly and Ming, survive for a time by sticking together and living in a dark boiler room until their lives are changed by meeting Mother Cabrini. The author, who is a Catholic homeschooling mother, has included questions and other study helps in the areas of history, geography, vocabulary and religion. The author has also produced a sewing kit for making a Mother Cabrini habit (complete with cross and rosary) for "American Girl"-type dolls and related craft and activity books which are available from the publisher.
