Following the horrific events on Caprini, Sharpe and his elite team of hard, witty, and trigger-happy Space Marines must now make their way to the frozen planet Mezzo to investigate the next Ma'har activity. What they will come across will go against their expectations as they confront the giant man-eater, the cyborg underground city, a horde of deadly extraterrestrial beings, and perhaps even the ever-elusive Ma'hars.
