Wulfgard: Knightfall. Wulfgard: The Prophecy of the Six, #1

Few can match the fury of Sir Tom Drake in battle - not even a Demon of Wrath. When Tom killed just such a fiend in single combat, a feat far beyond most mortals, he became the Demon Slayer. To the people of his beloved city of Illikon, Tom is a hero. But his city swears fealty to the Achaean Empire, and to them, he is just another knight. Enter Sir Scaevius, Left Hand of the Emperor. With war raging against a barbarian alliance massing to the North, Scaevius takes command of Illikon's armies and orders Tom on a suicide mission.
Tom obeys, but not without protest. Soon, he finds himself fighting not only barbarians, but his own superiors as well... and something else. Something supernatural. A monster is stalking him: a half man, half beast abomination from legend... a werewolf. It haunts his dreams and even his waking hours, and he starts to suffer blackouts, unsure what is real and what is nightmare. Hated by his superiors, hunted by beasts and assassins, Tom Drake must fight for his home, his life, and even his mind.
The events that are about to unfold will change his life, and the world, forever.---A thrilling tale of adventure, dashing heroics, chilling horror, alluring mystery, and exciting battles on both the personal and the grand scale, Knightfall takes you to the edge of your seat on a wild ride set in a dark age heroic fantasy world - a world where all myths are true, and monsters from legend seek to devour Men.
