Waiting for the Violins — Justine Saracen

Antonia Forrester, an English nurse, is nearly killed while trying to save soldiers fleeing at Dunkirk. Embittered, she returns to occupied Brussels as a British spy to foment resistance to the Nazis. She works with urban partisans who sabotage deportation efforts and execute collaborators, before resistance leader Sandrine Toussaint accepts her into the Comet Line, an operation to rescue downed Allied pilots. After capture and then escape from a deportation train headed for Auschwitz, the women join the Maquis fighting in the Ardenne Forests.
