A Warrior's Sacrifice

From the dust jacket:

Human. Outsider. Traitor.

Corwin Shura does not belong. After his family is killed playing both sides of the war that rages across the face of Earth, he is taken in by the very people who orphaned him.

Now, with his own soldiers to lead, Corwin is thrust back onto the battlefield to hunt down those that harry the fragile borders of the Republic of Humanity.

When the discovery of an alien artifact forces Corwin and his team into the service of an uncaring alien empire, he must lead his unit to death’s very door and back again.

Yet for Corwin, the physicality of war is easy. It is the emotional strain that he finds his greatest challenge - one he is ill-equipped to overcome.

And this is war, and in war people die.
