Glory Boy by Rick Partlow

Caleb Mitchell gave up everything to protect his home. Shunned by friends and family for abandoning the pacifist beliefs of their religion, he left his homeworld to fight against the implacable alien threat of the Tahni Imperium. When a training mission with a crew of military academy cadets winds up caught in the middle of one of the worst battles of the war, Cal and his fellow students are officially declared dead.
That’s when their war really begins. Recruited for a top-secret special operations unit, Cal and his friends undergo experimental augmentation that turns them into supersoldiers, designed to take the fight behind enemy lines and put the fear of God into an alien society who thinks their Emperor is God personified.
Caleb sacrificed his humanity to protect his people. But when his home is threatened, will he risk everything to save the people who turned their backs on him?
