Conan the Barbarian by Michael A. Stackpole

Born in the fires of battle, Conan of Cimmeria lost his father and village when they were slaughtered by the cruel warlord Khalar Zym. Wandering the world alone, Conan was forged into a peerless warrior by hardship and bloodshed.

Years later, he crosses paths with Zym and his armies. But before Conan can exact vengeance, he must contend with the warlord’s daughter-the seductive witch Marique-and a host of monstrous creatures. Only then will Conan’s quest bring him face to face with Zym in an epic battle to avenge his people and save the world.
