High adventure as only Lin Carter can tell it!
Under the trackless sands of the Sahara lies Zanthodon. That vast subterranean realm is the final homeland of the one-time masters of the world's surface - great dinosaurs, mighty jungles, and the living bands of primitive peoples from Neanderthals to Ancient Minoans and even Barbary Pirates!
It was into the cruel hands of those feared corsairs that Eric Carstairs' beloved cave-maiden, Darya the Cro-Magnon princess, had fallen. It was his mission to save her, as well as to keep his caveman friends and his professor guide from the innumerable dangers spawned in the unmapped wilds of the Underground World
Lin Carter (1930-1988)
Lin Carter is the working name of US author and editor Linwood Wrooman Carter, most of whose work of any significance was done in the field of Heroic Fantasy, an area of concentration he went some way to define in his critical study of relevant texts and techniques, Imaginary Worlds (1973). Born in St Petersburg, Florida, Carter was an avid reader of science fiction and fantasy in his youth. He was also quite active in fandom. Carter served in the United States Army between 1951 and 1953, after which he attended Columbia University. He is best known for editing the Ballantine Adult Fantasy series in the 1970s, which introduced readers to many overlooked classics of the fantasy genre, including James Branch Cabell, Lord Dunsany, Hope Mirrlees and Clark Ashton Smith. He began publishing sf with "Masters of Metropolis" for the Magazine of Fantasy and Science Fiction in 1957, with Randall Garrett, and the story "Uncollected Works" (1965) was a finalist for the annual Nebula Award for Best Short Story. He resided in East Orange, New Jersey in his final years, and died in nearby Montclair, New Jersey.
