The Swords of Night and Day — David Gemmell

Throughout the war-torn lands of Drenai, men and women live in fear of the Joinings, abominable meldings of man and beast, and of their mistress, the sorceress known as the Eternal. The Drenai's only hope may lie with a warrior long dead. For years Landis Kan has searched for the tomb of Skilgannon the Damned. But when he gathers the bones and performs the mystic ritual, the reborn hero is an enigma whose fighting skills are blunted and whose memories are fragmented. This Skilgannon is a man out of time, marooned in a world as strange to him as a dream. Still, he is not alone. Even as an ageless evil threatens to drown the Drenai lands in blood, two legendary heroes will lead the way to freedom.
