I wanted to learn more about the recently-beatified Father Solanus, and this book did give me information. But once in the Capuchins, Fr. Solanus had a relatively quiet, though admirable, life. He listened to people's problems, prayed for them, gave them advice, prayed, and played the violin (badly, apparently). Sadly, it seemed that he did not have very warm relationships with many of his religious brethren.
In any event, to produce a book-length work, the author resorted to reporting each cold from which Father Solanus suffered, and to quoting some not-too-miraculous responses to his prayers (as well as a number that were remarkable). So the book became a little tedious.
Also, Fr. Solanus was a friend of the controversial, pro-Nazi "radio priest," Charles Coughlin. The author mentioned this without comment. I found that a little disturbing, though I assume Fr. Solanus did not share Coughlin's extreme views. (The author did briefly refer to Fr. Solanus's anti-FDR view, though.)
The book helped me achieve my objective, however!
