The Undying Wizard

If any man has earned peace, that man should be Cormac Mac Art, exiled son of an Irish king, freed after years of outlawry from the shame of a crime falsely laid at his feet, exonerated by the High King of Eirrin.

But Cormac's troubles have only begun, as he finds himself staked by an evil sorcerer from the dim past, an occult nightmare who has sworn revenge.
