This was a great biography about the life of Miguel Pro until the very end when the author seemed to lose interest. Muller made a significant effort to capture his personality and include anecdotes from his life to effectively portray his personality. On the other hand, the book neglects much context about the events going on in Mexico during this time and how they affected Pro's life, vocation, and actions. He also summarizes one of the most impactful portions of his life - the last few days, martyrdom, and aftermath in about three paragraphs. It was a disappointing end to a good book.
