Brothers of the Fire Star - Douglas Arvidson

Joseph, nearing his thirteenth birthday, was exploring the jungle near his home in Guam when he heard the planes and the distant thunder of bombs, and knew that life would not be the same again. He hid as best he could. He awakended the next morning to a voice telling him he must escape to the sea; that he must find Napu, and together they must learn the ancient ways of navigating the Pacific if they were to survive the war.
