Francis of Assisi by Augustine Thompson, O.P.
Thompson tells the story of Francis's rebellion against his father, his struggle with leadership, his friendship with St. Claire, and his love for animals. I especially liked the anecdotes about St. Francis's idea of the model of the nativity for Christmas, and his concern that the animals should also be fed at celebrations. I also liked reading about St. Claire, and I hope that Thompson writes a book about her too.
The bibliography will be extremely useful, because I find St. Francis fascinating, and I certainly want to read more about him!
