Jason's army defeated the slugs on Bren and now, fifteen years later, he finds himself once more commanding an invasion force. This time they must expel the Slugs from a small moon, where they decimated the human inhabitants. And although Earth has finally begun to mobilise against the aggressors, a new and problematic faction has arisen. The totalitarian government of Tressel, a strategically-situated planet, is willing to defeat the Slugs at any cost - regardless of the human casualties. Unfortunately for Jason, his godson, Jude, is attracted to Tressel's total-war policies. As the struggle continues, Jason is not only fighting for the survival of the human race, but for his relationship with the only family he has left.
