(Coronet Books, March 15, 1991)
Born the bastard son of a Welsh princess, Myridden Emrys-- or as he would later be known, Merlin-- leads a perilous childhood, haunted by portents and visions. But destiny has great plans for this no-man's-son, taking him from prophesying before High King Vortigern to the crowning of Uther Pendragon -- and the conception of Arthur, king for once and always.
