Suddenly America is at war, Ruby’s longed-for Christmas trip is cancelled, her father wants to join the Army, and her best friend Emiko is getting shipped away to a Japanese internment camp just because of her heritage. A new friend’s family fled from the Nazis in Europe and can’t find out what happened to the relatives they left behind. Ruby watches in horror as her Japanese classmates are discriminated against and sent away. She can’t put a stop to everything that’s happening, but can she and her friends keep a song in their hearts until the world comes back to its senses?
