Loved. It. I couldn't put it down. I love Joe Ledger. I feel like such a fangirl lol. This book was absolutely fascinating to me. I have a lot of interest in the Holocaust and the way that one crazy persons (Hitler) thinking can destroy a nation, culture, and try to eliminate an entire race of people. I knew about a lot of the experiments they had done such as the effects of hyperthermia and that a lot of the research is was kept and the scientists given amnesty. Josef Mengele wasnt just crazy he really was evil. To have all these things come together in this book was good. A whole new generation will hopefully learn from the mistakes of the past. We should never forget.
