The Pnume (Planet of Adventure, Vol. 4)

This, the fourth and final novel of Jack Vance's classic series of the Tschai - Planet of Adventure, is complete in itself but presents a surprising and exciting climax to Vance's greatest creation.

The Pnume were an ancient race of the planet Tschai, living underground in a vast network of caverns with their human slave-species, the Pnumekin. The Pnume were the historians of Tschai, collecting its past with ruthless and scholarly dedication. Surface dwellers never saw the Pnume -- if they were lucky. Adam Reith was not so fortunate. The Pnume had heard rumors of a strange man claiming to have come from the planet Earth, and they wanted him for Foreverness, the museum of Tschai life. Adam Reith was about to become an alien exhibit.
