March 12, 1938, is a dark day. Hitler’s evil sweeps across Austria, destroying all in its path. Although violinist Elisa Lindheim is safe in Czechoslovakia—for the moment—she grieves over her beloved Vienna. Swastika flags now wave from every window. Jewish shops are destroyed. Neighbors’ houses stand empty. The Jews and those who try to defend them are arrested or killed.

The clock is running out for those the Nazis consider enemies of the state, such as journalist Walter Kronenberger and his five-year-old son, Charles. If Elisa agrees to help Charles and his twin brother, Louis, she could become useless to the Jewish Underground. Yet how can she stand by and watch two children fall into the clutches of the Nazis?
