The Gem of Notna has been dormant for decades, but now it has chosen its next host — an archaeology professor. Dr. Jack Corbett is now all that stands between the world and the mad Underworld king Seraphus. The Earth is doomed…unless it isn’t?

NOTNA, where INDIANA JONES meets BUFFY THE VAMPIRE SLAYER, is proof that anyone can save the world — or die trying.
