The Blood Stone: Curse of the Drakku Book One by Jason J. Nugent

He slays dragons for a living. Now he’s on a mission to wipe them from existence.
Lailoken longs to slit the throat of the beasts who abducted his wife. And with the winged monsters raining havoc on the northern lands, the vengeful dragonslayer’s bloody skills have never been in higher demand. Finally granted the chance to rescue his long-lost love in exchange for a dangerous, magical gem, he sharpens his sword for the quest of his life.

Venturing deep into enemy territory to collect the dragon-killing artifact for his fanatical leader, Lailoken prays that he’ll have one more chance to hold his beautiful bride. But as his single-minded hunt for revenge reveals a darker truth, he fears he may be fighting on the side of evil.

Will Lailoken reunite with his love and slay dragonkind, or has he unwittingly triggered the realm’s destruction?
