Used book – The Jackal of Nar, John Marco, Michèle Zachayus

To the Emperor of Nar, he is his best general. He leads his elite troops into the wild tribes of Lucel-Lor to support the corrupt and artificial power of his master. To Tharn, the religious leader of Lucel-Lor, he is the "Jackal of Nar," the one who brings destruction and death. A tyrant who wants to break magic, tradition, and secular gods. But to himself, he is merely a pawn in a game beyond his control. Prince Richius Vantran is neither an invading monster nor a glorious conqueror. Manipulated against his will, engaged in a deadly war bogged down in mud and trenches, he sees no way out of the conflict. If he wins, he damns himself by defending a cause he abhors. If he fails, he will lose his title, his kingdom, and his honor. And when love comes into play, there is no god or master... this time, the jackal will fight for himself!
