Talons of Scorpio by Alan Burt Akers

Finishing the job of destroying the hideous cult of the Leem is just one of the problems confronting Dray Prescot. For he must also rally all the world's forces to combat the onslaught that is on its way from the unexplored Southern Hemisphere. While rescuing kidnapped children from the altars of sacrifice, Dray finds himself fighting side by side with his own worst enemy, his renegade daughter, Ros the Claw, who has 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.

Talons of Scorpio is the thirtieth book in the epic fifty-two book saga of Dray Prescot of Earth and of Kregen by Kenneth Bulmer, writing as Alan Burt Akers. The series continues with Masks of Scorpio.
