The Hour Of The Dragon
Conan, the barbarian king of Aquilonia, has faced many threats to his throne — but none more deadly than a traitorous alliance of usurpers backed by the resurrected sorcerer Xaltotun, at whose command mountains crumble! Stripped of everything he held dear, Conan must fight his way out of a villain’s dungeon, across battle-ravaged countries, and back to his throne. Along the way, he meets Zenobia, the wily harem slave who will one day reign at his side.
