I thought this was a good book and enjoyed reading it, but the writing seemed a bit disjointed and there were times I had a hard time following the narrative. In addition, I thought he took a number of cheap shots at the Catholic Church without supporting evidence and, in some cases, contrary to the evidence, as with Pious XII. This would be a good introductory book for those who have not studied WWII and the Nazis but it would be less appealing to those who have a good overall knowledge of this period. This, from a Bill O'Reilly admirer, most of the time.
