"[You are] either a German or a Christian; you cannot be both."

Adolph Hitler's ominous statements seem only a distant threat to eleven-year-old Rudi Kaplan. But when the Nazi forces invade Poland and bomb his home city of Warsaw, Rudi finds out that he is Hitler's enemy not only because he is a Pole but also because he's a Jew and a Christian.

The next few years change Rudi's life forever. With only his imprisoned father's promise that they will be reunited after the war, Rudi must learn how to survive in hiding, how to be truly brave, and how to overcome the hatred of his enemies. He must learn to die to himself and to trust the God who is mightier than any army.
