<b>From the back cover of the Lancer second printing:</b> Beasts, men or aliens? In that hidden valley, land of strangely forbidding beauty, Eric Nelson, soldier of fortune, faced a battle weirder and more savage than any he had ever fought.
<p>He was hired to fight for humanity, against beings that seemed to be both more and less than human.
<p>The weapons of the enemy included centuries-old powers of magic and superstitions... but Nelson fought grimly, even when his mind was helplessly trapped in the body of a wolf.
<p>Then came the climactic test of his allegiance, the knowledge that more than just humanity was at stake... and the final mind-shattering discovery of the alien secret that lay buried in the Caverns of Creation!
