This was an very fun. The structure and manner of telling the story here was very cleverly done. The book is divided into basically three parts. The German/Austrian/Polish characters lead up to the year of the rescue, then the American lead up, then the rescue and the fallout itself. Elizabeth Letts does a great job of making you care, and keeping you hooked in. She does take some creative license with behavior thoughts, and scenes but overall it's a very engaging and rewarding reading experience.
If it's a time/topic that interests you I really recommend it. It was really good.
