The Eighth Sword

"The Eighth Sword follows The Swords of Athos. It begins when a young
merchant, Adrian, is captured by Genghis Lin to steal the magical
sword of Ibernia from his cousin, Antoine. Genghis can’t defeat his
arch enemy, King Leopold, unless this sword is disabled. After refusing,
Adrian is saved by the mythical gods and sent with Antoine to find the
magical sword of Amazonia, an eighth world that has just been discovered
and is threatened by the evil wizard Xena. Things immediately go awry,
forcing the gods to summon all the keepers of the swords. Join these heroic
men on their adventurous quest to keep peace in the worlds."
