This third book in Edgar Rice Burroughs' Moon Sequence (preceded by The Moon Maid and The Moon Men) finds Julian 20th, The Red Hawk, leading the last Americans, now a primitive nomadic people, to a final skull-splitting confrontation with the dread Kalkars, the Moon Men who enslaved humanity with the help of traitor Ortis in the previous volumes. The pace is relentless, the fighting is fierce, and The Red Hawk with his trusty horse Red Lightning is determined to drive every last Kalkar into the sea, if it's the last thing he does!
