This is an incredibly well-researched story full of details about the nuances of life in Nazi Germany for Christians, their own often-ignored victimization, and a lot of cinematic moments of defiance from the very biography-worthy protagonist while condemning Nazism in a fiery yet relational that makes it even more sad and baffling than ever about why we have so many modern Neo-Nazis. The author does an excellent job of pointing out the historical complexities of life in both that place and that time that are easy to overlook from a historical perspective.
At the same time? The author can occasionally repeat himself while returning to a point after a diversion, his arguments and logic for why the Bishop did little for the Jews have some elements of wishful thinking, and the debunked Clean Wehrmacht Myth gets accepted as reality at one point. So not a perfect book but still one that tells some important stories and tells them well, and I think that would be true whether you are a Catholic reader or not.
