Corrie and Betsie ten Boom are middle-aged sisters working in their father's watchmaker shop in pre-World War II Holland. Their uneventful lives are disrupted with the coming of the Nazis. Suspected of hiding Jews and caught breaking rationing rules, they are sent to a concentration camp, where their Christian faith keeps them from despair and bitterness. Betsie eventually dies, but Corrie survives, and after the war, must learn to love and forgive her former captors.—Mark Hettler
