Beasts of Antares - Dray Prescot, #23

The marvelous adventures of Dray Prescot on Kregen, the world of wonders that orbits the twin suns of Antares in Scorpio, have become a science fiction saga to rival and perhaps surpass the works of Edgar Rice Burroughs and others of the heroic fantasy band. This lone Earthman, once a pawn of cosmic powers, now enters a new cycle of his fabulous career as he rallies the warriors of Vallia for a final stand against the foes that have encircled them.
And then, in an act of true Prescot bravado, he undertakes single handed to rescue three old friends from slavery in a distant land. The beasts of Antares are many and terrifying, but Prescot does not belong to the faint hearted. He will need every ounce of courage this time!Beasts of Antares is the twenty-third 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 Rebel of Antares.
