Hunters of the Red Moon - Paul Edwin Zimmer - Bog

For the Hunters, the Hunt was a religion. The Sacred Prey, sentient beings collected from all over the galaxy, were literally given a fighting chance--they were allowed to choose weapons from an armory with every imaginable weapon and given time to train. Then they were taken to the place of the Hunt, where death awaited them. Those who survived until the eclipse of the red moon, however, were honored by the Hunters and rewarded with all the wealth they could desire. The trick, of course, was surviving.
