"Thirteen-year-old Paolo Crivelli dreams of being a hero in Nazi-occupied Florence. . . . A superb historical thriller." -- Kirkus Reviews (starred review) Italy, 1944: Florence is occupied by Nazi forces.

As their mother is pressured into harboring escaping POWs, Paolo and Costanza each find a part to play in opposing the German forces. Both are desperate to fight the occupation, but what can two siblings -- with only a bicycle to help them -- do against a whole army?
