Half Persian, half Greek, Damon is captured and held hostage by the army of Alexander as the great warrior descends upon the Persian Empire. Trained as a cadet, Damon follows the Greek army through Tyre, to Bactria to Babylonia, always searching for his brother Leon fighting on the side of Darius. With Darius' death, his army divides its support and Leon dies just as Damon finds him. With Bessus of Bactria in power, Alexander is spurred on to further battle. Against this background, Damon has many adventures, all of which slowly lead him to a recognition of Alexander's greatness. Thus, when he is discharged from service, he chooses to remain with the conqueror. Some exciting moments occur in a story in which character motivation is never fully developed. Essential to comprehension is some knowledge of this era.
