How do you reconcile a decision you made in the past when the world erupts in war, threatening the life of someone you love and believe you were protecting?

Adrian Mazurek immigrated to the United States from Krakow, Poland, 14 years ago and is now a successful violin soloist and the concertmaster of the Eleventh Union Symphony Orchestra in New York.

But despite his outward success, Adrian is inwardly harboring a shameful secret, one he has not revealed to anyone.

However, that is about to change. Adrian plans to propose marriage to Suzanne, but knows he must tell her the truth about his past before doing so. Riddled with guilt and shame, Adrian can barely look at himself in the mirror. How can he look Suzanne in the eye and tell her that he left his infant son, Simon, in the care of his aunt and uncle in Poland 14 years ago?

If only confessing the truth to Suzanne was the most difficult part.

Adrian soon learns that Germany has invaded Poland and that World War II has begun. Fearing that the Germans will learn that his son is of Jewish heritage, Adrian must do something to ensure Simon's safety. But what? And will Suzanne stand by his side or will she turn away because of his deceit?
