Even though I know the book was fictional, I know countless true stories really happened like this, and the people who endured such inhumane evil still found the courage to try to do what they could to undermine the Nazi government-- that is truly inspiring. Mr. Rosenburg has again created a masterpiece. I always enjoy his writing, and this is destined to be a classic. He crafted a thrill ride of a read, that makes you feel as if you are there-- a silent witness to the characters' heroism and persistence. This a definite read again for me.
