Arlo is the son of Aton, conqueror and victim of a dreaded Minionette. Arlo has known no world but the cavern-world. When war comes to the caverns he is a confused spectator. Men, women, and other creatures bearing exotic weapons invade. The women fascinate Arlo-they seem disturbingly familiar to him. Well they might. For these beautiful, identical, fiery-haired and smokey-eyed savage warriors are minionettes-figures of terror and dread on all civilized worlds. And they are his kin. Arlo's fate is to battle them and the superintelligence of Chthon at once, to work out a destiny shaped by a god more ancient than mankind-the destiny of the galaxy as well as his own.
