Description: Morton Cargill is about to die for a crime he committed 400 years ago.

Lieutenant Morton Cargill was brought from the past to be punished for his crime, an accidental murder that took place centuries before. Now he is in a world ruled by the Shadows, an evil people who can pass through solid walls and remain untouched by weapons. But the Shadows are being threatened by the Planiacs, a celestial race that lives high above the earth and to whom the preservation of Cargill's life means their own existence.

Now Cargill is hunted by one race, held captive by the other, caught in a deadly clash of minds and machines -- in a terrifying world where he doesn't know the rules!
