Conan And The Emerald Lotus

One wizard is bad. Two are a disaster...And a deadly disaster, too. For Conan, after refusing to help the evil wizard Ethram-Fal, has been cursed with a spell that is slowly, inexorably squeezing the life from his mighty frame.
The only person who can banish the spell--besides Ethram-Fal, of course--is the sorceress Zelandra: a raven-haired beauty who practices only white magic...or so she says. Zelandra has offered to lift the spell from the Cimmerian, if only he will do her one small service: steal the deadly Emerald Lotus from the clutches of Ethram-Fal in his impregnable desert fortress.
No good can come of this, Conan thinks to himself. Once sorcery gets mixed up in it, the whole job goes to hell
Unfortunately, he's right.
