Talons of Scorpio — Alan Burt Akers

To finish the job of destroying the hideous cult of the Leem was just one of the problems confronting Dray Prescot, Earthman on Antares' wonder planet. For he had also to rally all the world's forces to combat the onslaught that was on its way from the unexplored Southern Hemisphere.

While rescuing kidnapped children from the altars of sacrifice, Dray found himself fighting side by side with his own worst enemy, his renegade daughter, Ros the Claw, who had pledged his death. Caught in the talons of fate, he would first have to unravel that vicious web or be torn asunder by monstrous adversity.
