Piedmontese Alps, in the crucial years of the Resistance. Marta is thirteen years old, she is skinny, not very shapely and has long blond hair that makes her look German. One day her brother Davide, slightly older than her, proposes to help the resistance against the Nazis and fascists, unbeknownst to the partisans themselves, who would not accept them at their age. David has a brilliant plan, but Martha feels small, she is afraid and is against the war. However, her brother also involves Marco, a companion with whom she is in love, and when he gets to know the partisans closely, Marta is fascinated by them. Thus she will find herself inside an adventure greater than her, which will expose her to frightening dangers, but will allow her to bring out grit, imagination and unspeakable courage, finally managing to upset the Nazi garrison in the area. Reading age: from 9 years.
