This was a great book that intertwines the lives of an American, A Polish victim of Nazi occupation, and a German doctor during WWII. Their stories are based on real events with the American and the German Doctor being actual people and the Polish girl representing a composite character of many who were in her same situation. The personal lives of all are fictionalized. 
 I enjoyed this book a lot it was fast paced and introduced me to yet more horrors that I hadn't known of from WWII. The fictionalized parts were a bit too neat and tidy but still it's a great story that made me want to look up more about the actual events and people.
