Arturo el Rey (Excalibur Regained Series)

Art Reyes, a young Marine, suffers eerie visions of dying with a lance in his chest-as none other than King Arthur. Was it only a legend-Arthur's promise to return when the world needs him? Then bio-terrorists unleash a plague that ravages the population and crumbles civilization. With marauding gangs vying for power, Art is launched into a leadership position as the one man with the charisma to unify citizens to fight back. Miles away, a young woman named Shanna struggles to survive the chaos of the new Dark Age. Fate inexorably draws the two together, the reincarnated King Arthur and Lady Guinevere. Their task: to restore order, rediscover their lost love and, this time, to get it right.
