The United States is at war, and sixteen-year-old Joseph Bruchac wants to join the cause- especially when he hears that Navajos are being specifically recruited by the Marine Corps. So he claims that he is old enough to enlist, breezes his way through boot camp, and suddenly finds himself in a top-secret task, one that's exclusively preformed by the Navajos. He has become a code talker. Now Joe must brave some of the heaviest fighting of the war, and with his native Navajo language as a code, send crucial messages back and forth to aid in the conflict against Japan. His experiences in the Pacific- from Guadalcanal to Iwo Jima and beyond- will leave him forever changed.
