Fires of Scorpio by Alan Burt Akers

Triple trouble always follows Dray Prescot, especially when he thinks he has things under control. This time, while involved with setting things right on the continent of Pandahem, the Star Lords yank him away from his friends and dump him, weaponless, at the gates of the terrible temple of the Leem. Rescuing a girl sacrifice is only the start, for next he has to help Pompino to torch all the temples of the Silver Wonder, and take to the sea to confront the next wave of the fish-headed marauders from Kregen's Southern Hemisphere.

Fires of Scorpio is the twenty-ninth 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 Talons of Scorpio.
