I'll bet, this will remain one of my favorite books ever for a long while. The author is brilliant and clearly a researching manic(examine those notes in the back). I was fascinated to learn about the Nazi's insane plans to revitalize extinct animals and flora. And, even while the horrible details of cruelty in the Warsaw ghetto and streets of Poland took me way down, the heroic lifesaving efforts by the insurgents and others restored my faith in humanity. Yes, there is such goodness in the world even in a time of pure evil. The main characters were human, likable and raw. This is a powerful and moving book.
