This is a biography of Kateri Tekakwitha before she became a Saint. While it has some facts, the author does say there are some characters and parts she made up since there isn't too much known about Kateri's life.With that being said, it is a good book even if some of it is made up. It's a good book to read to at least learn the facts that are known about Kateri's life. However, for customs and the actual lifestyle of Kateri's tribe, it might be best to do additional research to see if the author was accurate in her portrayal of the Mohawk people. Also, I would recommend reading other books about Saint Kateri to see what else could be learned about her.
