Except for a constrained beginning, this short novel gives a clear, understated picture of life in occupied France in the spring of 1944. Lee Cole, the twelve-year-old son of a French woman and a long-dead American hero of World War I, takes part in the pre-Normandy invasion activities of the underground. Clandestine translation of BBC reports, airplane drops of ammunition, and the climax of blowing up a vital German transmitting station are related without exaggeration and in detail. Suspense, teamwork, and planning, rather than horror, pervade this introduction to recent history for young boys.
