Warrior Mage — Guy Antibes

A SWORD OF SPELLS novel, at last!
The world of Kellar has only one warrior mage. That's okay, since there really aren't any wars. So Brull, our warrior mage, makes his living hunting down evil magicians as a bounty hunter. But as his personal life begins to change, and not to Brull's liking, the world begins to crumble as his evil nemesis, Heron, assembles all of the magicians to help him bring a god down to Kellar to rule the earth with Heron by his side.
What makes matters worse is that Brull's sister has been called to serve as Abbess at the Healer's Temple in the very city that Heron will perform his evil deed. The good gods are on Brull's side, but he finds that there is little they can do. It's up to him and a select band of others to save the day.
