Derek and his friends, living outside of London during World War II, regard the frequent air raids with more fascination than fear--after all, they can barely remember a time without them. The boys are thrilled when school is canceled for a few days due to a raid, giving them time to work on their secret camp. But when their camp is savagely attacked by a rival gang from the neighborhood, the harsh reality of the violence surrouding them suddenly crashes down upon Derek and his friends--and a long night of bombing changes his feelings about the war forever. Includes a reader's guide.
