By 1943, Anna Zadok, a Jewish Christian living in Prague, has lost everything, including her career as a concert violinist and almost her entire family. The only person she has left is her beloved grandmother, and she's determined to keep her safe. But protecting Grandmother won't be easy—not with a Nazi officer billeted below them.
Anna must keep a low profile. There's one thing she refuses to give up, though. Despite instruments being declared illegal, Anna defiantly continues to practice her violin. She has to believe that the war will end someday and her career will be waiting. Fortunately for Anna, the officer, Horst Engel, enjoys her soothing music. It distracts him from his dissatisfaction with Nazi ideology and reminds him that beauty still exists in an increasingly ugly world.
When his neighbors face deportation, Horst is moved to risk everything to hide them. Anna finds herself falling in love with the handsome officer and his brave heart. But what he reveals to her might break her trust and stop the music forever. . . .
