I enjoyed this book as an interesting story but it's definitely a fiction book with history mixed in. I have seen mentions here and there of German youth losing respect for their Nazi and/or collaborator parents when they learned the truth of the horrific depravity perpetrated by Germany during the war. This book imagines what a daughter of a Nazi doctor does when she begins to understand what her father was doing at a concentration camp and what it really meant to be a Nazi. Personally, I did find the book to be bit more drawn out than it needed to be so in that aspect, I would give it 3.5 stars. I did find myself bored with the same sort of scenes being repeated or the same flashbacks being told. Those types of things don't move a story forward and can make a book tedious to read. All in all, I would recommend it for a different take on post World War II novels. I should add, that I rated it based on it being a young adult book. If it was an adult fiction book, I would probably give it a 3.
