I feel like in this book the biggest theme is being anti-semitism. Almost like slavery, and there is a solid difference between the two. This is more of the European suppression of other races and religions. Survivors of the Holocaust are major informers of this topic. This book has a lot to do with this topic due to it being a novel about if the Germans won the war. I feel like this book is doing a good job of showing what it would be like if this was an issue now-a-days. I haven´t read any issue-driven books before but they are really interesting to read.
