Soldier, Ask Not: Dorsai, cartea 3

On the sixteen colonized worlds, mankind had changed, evolved into something that was slightly more than human...and slightly less. Men of War on the Dorsai worlds, men of Faith on the Friendly Worlds of Harmony and Association, men of Science, the Exotics of Kultis and Mara, and the Splinter cultures which had produced even stranger new talents. Those who knew said it was the Dorsai who supplied soldiers to the sixteen worlds. The Friendlies supplied cannon fodder, common soldiers who could be relied on to obey orders at all times. But even cannon fodder can sometimes produce genius. Jamethon Black is a true soldier, and a true man of faith. Now he must face a deadly enemy an enemy whose defeat will forever separate Black from the only woman he has ever loved."
