Eric of Zanthodon

Zanthodon is envisioned as an immense circular cavern five hundred miles wide, one hundred miles beneath the Sahara Desert, a refugium preserving various prehistoric faunas and antique human cultures that have found their way into it throughout the ages.

The story follows the improving fortunes of surface world explorer Eric Carstairs and his Zanthonian love interest Darya. It ends with them leaders of their own tribe, augmented by such other exiles from the surface as Niema and Zuma of the African Aziru tribe and World War II survivors Von Kohler, Bog and Schmidt, and heirs apparent to the leadership of Thandar and Sothar. They are now married and blessed with a young son, Gar.

Robert M. Price finds the book and series "not without their charming moments," but also sees in them "clear evidence of Lin Carter's increasing carelessness as a writer," exhibiting "an increasing tendency toward self-contradiction and incoherent conception—a greater sloppiness coupled with an exhaustion of imagination."[2]

Steve Servello, writing in Erbzine, calls the novel "the weakest in an extremely fine series," not a poor one but "anticlimactic," thinking the previous book "would have made an appropriate conclusion to the Underground World saga, save for a few loose ends." While these are resolved in Eric of Zanthodon, he deems "176 pages ... about 100 too many for this purpose."[3]
