The Mark of the Demons — John Jakes

Brak has entered the supernatural realm in which his mighty broadsword is useless. His bravery replaced by fear, Brak must find the strength to defeat the Mark of the Demons. Along the way, he must block out the seductive voices emanating from the desert; overcome the beauty of the deadly, mysterious twins; and defeat the fierce warriors of Quran. Can he muster enough bravery to realize his destiny, or will his fear be the death of him?
