It’s a familiar coming-of-age story, set in the summer of 1942. The country is at war, and Hermie, Oscy and Benjie, three teens from New York and New Jersey, are spending a summer on an island off the coast of Maine. The boys’ biggest concern is girls, and except for an air raid drill, a few cursory efforts at conserving goods, and a single, pivotal telegram, the summer islanders are relatively unaffected by the war.
