Inferno (Inferno, #1)

This is the 6th Pocket printing.
Cover Artist: Harry Bennett

An unearthly voice hisses unholy welcome. And the late, great Allen Carpentier begins his one-way journey into the dim nether regions where flame-colored demons wield diabolically sharp pitchforks and tormented vixens reign forever in a pond of sheer ice. Here, in this land of torment and terror, he discovers the amazing truth of the ultimate adventure that lies beyond the grave.

Frank Herbert -"The somber beauty of INFERNO brought up to the twentieth century with care and humor and with some sins Dante didn't even suspect."
