I think this was a book I needed. In it, the author wrestles with the great unsolved problem of theology, the problem of evil. In other words, if God is both all good and all powerful, why is there evil in the world? He takes us on a journey, surveying the great philosophers and theologians of antiquity and continuing right up to the current day with newer theories such as process theology and open theology, in a fairly objective fashion. Then he finishes with his own current conclusions and the reasons he takes this view. In that last section are some beautiful analogies to music with references to Tolkien and to the art of jazz playing that particularly appeal to me. All this is done in a very casual coffee-shop conversation style, with many references to current culture and entertainment that is accessible to readers at many levels. I had encountered some of this content on the author's podcast, "Deep Thoughts."
That said, if you are looking for a rigorous academic or scholarly book, this is probably not a fit, though the end-notes are interesting and helpful. There are also many places where a good editor might have guided him to different choices ... maybe this can happen in the 2nd edition. In the end, I believe he met his stated goal: to help readers understand how people in the past have thought about this problem and to see more clearly the strengths and weaknesses of of the assumptions they may bring to the reading.
