Too Bright the Sun by Lazlo Ferran

A man afraid of his own soul! Seeking revenge for the death of a friend ten long years ago, Major Jake Nanden has pursued his own personal demons with an almost religious fervour through life and through battle. He is a soldier so highly decorated that his fame reaches far beyond the desolate moon Io where he is stationed. His victories in the Jupiter Wars are hollow though, for he is a man scared of his own soul. His life seems to be a trap from which he cannot escape. His is the Replicant Company, and replicants are despised by all.
