George Henry Smith (October 27, 1922 – May 22, 1996) was an American science fiction author, who also wrote soft-core erotica. He is not the same person as George H. Smith, a libertarian writer, or George O. Smith, another science fiction writer. There were at least 3 authors writing as "George H. Smith" in the 1960s; one wrote many "swamp love" paperback originals, which are often erroneously attributed to George Henry Smith. Smith himself used the pseudonyms Jerry August, Don Bellmore, Ross Camra, M J Deer (with his wife, Jane Deer Smith), John Dexter (a "house name" used by multiple authors); George Devlin, Robert Hadley, Jan Hudson (a "house name"), Jerry Jason, Clancy O'Brien, Alan Robinson, Holt Standish, Diana Summers, Hal Stryker, Hank Stryker, Morgan Trehune, Roy Warren, and J X Williams (a "house name") for publishers such as Avalon, Beacon, Boudoir, Brandon House, Epic, Evening Reader, France, Greenleaf, Midwood, Monarch, Notetime, Pike, Pillow, and Playtime. It is known that he wrote more than 100 novels.
Kar Kaballa, The Second War of the Worlds, and The Island Snatchers are a series featuring a protagonist named Dylan MacBride, and set in the land of Avalon on Anwwn (a parallel to Earth). The first was published by Ace Books, and the others by DAW Books.
According to a legend, Avalon is the place where King Arthur was taken when he was dying. In Avalon, Earth is a place of legend, separated from Avalon by a dimensional gateway, and what is legend in one place is real in another.
In Kar Kaballa, Dylan MacBride, the son of a famous Avalonian explorer, attempts to warn the Empire in which he lives (fairly similar to the late-19th century British Empire) of an impending invasion by the Gogs. The Gogs are a nomadic race equivalent to the Mongols, living on a continent separated from Avalon by a narrow sea. Their ruler is Kar Kaballa, and they worship a deity named Cythraul who demands human sacrifice and wishes to emerge and consume the world.
