This Crooked Way (Morlock Ambrosius, Book 2)

Travelling alone in the depths of winter, Morlock Ambrosius (bitterly dry drunk, master of all magical makers, wandering swordsman, and son of Merlin Ambrosius and Nimue Viviana) is attacked by an unknown enemy. To unmask his enemy and end the attacks he must travel a long crooked way through the world: past the soul-eating Boneless One, past a subtle and treacherous master of golems, past the dragon-taming Khroi, past the predatory cities of Sarkunden and Aflraun, past the demons and dark gnomes of the northern woods. Soon he will find that his enemy wears a familiar face, and that the duel he has stumbled into will threaten more lives than his own, leaving nations shattered in its chaotic wake. And at the end of his long road waits the death of a legend.
