Behind the Bedroom Wall — Laura E. Williams

It is 1942. Thirteen-year-old Korinna Rehme is an active member of her local Jungmadel, a Nazi youth group, along with her best friends. She believes that Hitler is helping Germany by dealing with what he calls the "Jewish problem." Korinna, however, has a rude awakening when she discovers that her own parents are hiding Jews behind the wall of her bedroom. At first, she believes her parents are traitors, but as she comes to know the Jewish family, her sympathies begin to turn. When someone tips off the Gestapo, loyalties are put to the test and Korinna must decide what she really believes and whom she really trusts.
