3.5 stars. Took me forever to finish this book: school and other work interrupted my reading. 
 As for the book: it's really well done. I thought that Werner was the more interesting character to follow. Ultimately, I don't think this book brings anything 'new' to the historical (WW2) novel, but as I said, it's very well written, has great characters and I can totally see the appeal this book has.
