Well sourced and thoroughly treats, as far as I can tell, the relevant details that we know about Saint Dominic and the course of his life.
That said, I left feeling like I had more questions than answers, and I don't know if I'll be adequately able to express what I mean. The book treats the various deeds or works of Saint Dominic, as well as his companions, but felt like it spent relatively little time fleshing out his personality. The best details on that front had to do with descriptions in his habitual fasting, or the ways in which he would pray. Often the author will describe the ways in which close companions to the Saint described him, which in the end made me wish I had gone and directly read them in the first place. In addition, the book is full of diversions for the author to lay out his takes in various topics, which I actually love and think gives a work alot of charm. But in this particular book, again hard to really articulate, the diversions often felt more like they were getting in the way of my getting to know the Saint, over however much character they gave to the book.
I would recommend the read, it was a good book and Saint Dominic is a wonderful saint Worth getting to know. Maybe I'll check out those primary sources next.
