STAR GUARD By Andre Norton Cover by Ed Emshwiller - Kana Karr was a young swordsman, a wielder of a medieval weapon in a super-scientific galaxy of limitless destruction. As an Earthman, he was nothing more than a hired mercenary sent to kill or be killed at the command of the oppressive Central Control. - On a seemingly routine police action to the planet Fronn, Kana learned of a plot that threatened to overturn the balance of power held by the Galactic authority. The liberation of Earth might hinge on the outcome of the plot!

Habitable worlds were so few and far between-and so often claimed by inhospitable aliens. Why the antagonism? Why the lack of suitable volunteers, when their destination might provide the long-sought solution?
