Hanna is a talented pianist, and the protected second daughter of middle class Hungarian Jews. Relatively late in World War II the Budapest Jews were rounded up and sent to Auschwitz. Hanna and her mother and sister are separated from her father. Her mother becomes increasingly mentally ill until she too is taken away somewhere. Her sister Erika is slowly starving to death. Hanna is quite a naive 15-year-old but when presented with the opportunity to play piano for the camp commander, she is desperate to be chosen. She goes each day under guard to the commander's house and stands waiting in case the commander should want some music. Also living in the house is the commander's son, Karl. A handsome young man who seems completely disengaged from what is happening around him. Hanna hates him as he sits drawing in the music room. But the longer Hanna goes to the house, the more she realises there are other things going on. Secret things. Karl may not be the person she thinks he is. Before she knows it she has fallen in love with the wrong boy.
