London Calling
by Edward Bloor

John Martin Conway feels out of place at his exclusive prep school, where he is constantly reminded that he is a scholarship kid. After a confrontation with Hank Lowery, the great-grandson of the schools founder, he requests to work at home on an independent study project. The World War II-era radio that his grandmother left him brings him into contact with Jimmy, a boy who lived during the war and who needs his help. He takes Martin back to the time of the London Blitz.
