The planet is called Banshee. The air is unbreathable, the water poisonous. It is the home of the most implacable enemies that humanity, in all its interstellar expansion, has ever encountered. Felix is a scout in A-team Two. Highly competent, he is the sole survivor of mission after mission. Yet he is a man consumed by fear and hatred. And he is protected not only by his custom-fitted body armor, the culmination of ten thousand years of the armorers' craft, but also by an odd being which seems to live with him, a cold killing machine he calls "the Engine." This bestselling science fiction classic is a story of the horror, the courage, and the aftermath of combat and also of how strength of spirit can be the greatest armor of all.
