I had higher expectations for this book based on it’s popularity and the reviews. I found it overly simplistic and did not feel the characters were well developed. It was without any new insights. I found some of the story improbable and was therefore not surprised to learn of the many historical inaccuracies. I think the author or editors could have done a better job of fact checking. In the end I also felt that the two main characters were collaborating with the Natzis and that this behavior continued with collaborating with the Russians after the war. Would have been a better read if this aspect of survival had been explored more.
