The prior novel, Zanthodon, ended in a cliffhanger as Darya was captured by Barbary Coast Pirates. In this novel's beginning, both Eric and Professor Potter (both men from our present-day USA) have been snatched by what the folks of Zanthodon refer to as Dragonmen. They earned this title because they wear magic armbands that allow them to telepathically control dinosaurs! So, these Dragonmen capture Eric and Professor Potter and take them across miles of Zanthodon's baked Earth to the Scarlet City of Zar. There, the two meet the Sacred Empress of Zar, a woman named Zarys (who is like the twin-sister of Darya).
Meanwhile, Hurok and Jorn the Hunter embark on a rescue mission to retrieve their friends from the Dragonmen. This side-story adventure has the two facing near-death experiences as they cross a treacherous mountain pass called the Wall of Zar and an inland sea known as the Lugar-Jad. Additionally, there are other side-stories that involve a guy named Garth searching for his daughter Yualla, and Tharn searching for Darya.
Make no bones about it, Hurok of the Stone Age is a convoluted novel packed with alternating side-stories within chapters that make up “parts” of the book. Often, I lost track of who the characters were, which tribe or type of people they represented. When you have characters that are Zarian, Drugar, Sagoth, Cro-Magnon, Thanadar, Gorpaks, etc., I nearly needed an organization chart to just figure it all out. At one point, I decided to just enjoy the adventure and let it all just sort of flop over my head on the who's who battle for clarity. In doing so, I found I really enjoyed the book, particularly Professor Potter's participation in the narrative and his quest to bring gunfire to this bizarre world.
If you enjoy Lin Carter's absorbing, self-indulgent storytelling – high on character count, exotic locales, plot holes a mile wide – then this is a really fun read. Punt the logistics, suspend disbelief, and look over the convoluted meshing. In doing so, you'll not only love this novel, but appreciate the entire series.
