In 1943 Poland, the Nazis have forced Natia and Teodor from their peaceful farm to the harsh confines of a labor camp. When the couple is separated, Natia is chosen to be the housekeeper for the camp’s overseer, and Teodor is sent to work in the factory. Despite the strict camp rules—and the consequences for disobeying them—Natia finds a way to communicate with Teodor by sending messages through song as she passes Teodor’s dormitory.

The stakes get higher when Natia finds a Jewish orphan on the overseer’s doorstep. She is determined to protect the boy and raise him as the child she and her husband were unable to bear—but if her German captors discover how much she’s hiding, both she and Teodor may pay the ultimate price. .

It’s 1943 and Anna Zadok, a Jewish Christian living in Prague, has lost nearly everything. Most of her family has been deported, and the Nazi occupation ended her career as a concert violinist. Now Anna is left to care for her grandmother, and she’ll do anything to keep her safe—a job that gets much harder when Nazi officer Horst Engel is quartered in the flat below them.

Though musical instruments have been declared illegal, Anna defiantly continues to play the violin. But Horst, dissatisfied with German ideology, enjoys her soothing music. When Anna and her grandmother face deportation, Horst risks everything to protect them.

Anna finds herself falling in love with the handsome officer and his brave heart. But what he reveals might stop the music forever.
