Jason Wander
Book 4: Orphans Alliance

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.
