Whirling out in space, the spacecraft ALPHA-ARK is doomed. The ship's complex life-support systems have malfunctioned and no one knows how to repair them. Without the machines there can be no food. The crew will starve, their ship condemned to travel the infinite universe for eternity. The discovery of a secret computer reveals the truth of their past and the fate that awaits them if the ship should land. They are not alone on the Ark. The masters who would enslave them lie sleeping, frozen, ready to rise again.
"They discovered the location of the cocoons. The bodies were frozen intact. Sebrum eyed them and an idea passed his brain. Meat was meat, anything was better than starvation. They allowed the corpse to thaw and then began to devour it."
