Allies of Antares. Dray Prescot, #26

Beneath the two suns of Antares, the planet Kregen is truly the wonder of the universe. For there, at the inscrutable planning of unseen powers, are gathered members of the great races of the galaxy. There, too, were natural humans, and their strivings and ambitions colored and led the struggle to create a world of peace. Dray Prescot, Earthman, had been brought there as an agent of the Star Lords, but he has made himself into a rallying point of strength.
Now, after the worst war between the humanoid lands has finally concluded, Prescot again confronts the Star Lords, only to learn that the hard won peace is just a transition to a great hemispheric invasion that was even then raiding over the horizon. This book contains a glossary of the Spikatur cycle. Allies of Antares is the twenty-sixth book in the epic fifty-two book saga of Dray Prescot of Earth and of Kregen by Kenneth Bulmer, writing as Alan Burt Akers.
