Newbery Award-winning, New York Times best-selling author Avi recreates the sights and sounds of wartime Brooklyn in this fast-paced story. Like every student in Miss Gossim's 1943 fifth-grade class, Howie Crispers has one thing on his mind: World War II. When he isn't in school, Howie stays busy watching for Nazi spies. So when he notices his principal acting suspiciously, it's his patriotic duty to investigate. But what he discovers is far more devastating than any headline at the newsstand.
