Query: First and second half deserve different ratings

I agree with others who point out how the beginning of the book is good but the latter part takes a turn for the worse as the religious messaging becomes blunt and distracting. I decided to read this because I have an interest in World War II that goes back several decades to my pre-teen years. I've consumed as many non-fiction sources as I could get my hands on and set aside time to read or watch, and have watched some "historical fiction" movies, so I thought I'd try a historical fiction book, especially since it was presented as a well-researched work focusing on the aftermath in Europe, which is not something I've read much about. I gathered that there might be a religious element to the story, but I did not expect the focus to shift so much to that. The first part was a reasonably enjoyable read, but the second part left me with a negative overall view of the book. I only finished it because I don't like leaving books unfinished.
