They have gathered now on Damien and are about to witness the last rising of a manmade nova. They are 16 humans in a distant world about to be enveloped by an eruption of violence--horror and murder oddly complemented by a bizarre unforgiving love. But justice is not all that's about to be found. Judgment is coming and the 16 unsuspecting ones are on the threshold of the murdered star.
