The Twist — Richard Calder

John Twist, gunslinger, prowls a landscape that is a weird mix of Wild West and science fiction pulp tales. In the aftermath of the Venusians' arrival on Earth in the 1950s, a "psychogeographic event" occurs, separating the old Wild West from the rest of the planet. There, Boot Hill and Tombstone are alive as they once were, without the interference of modern technology. Twist must fend off the advances of Miss Viva Venera, a Venusian necrobabe, as well as the more murderous designs of the sinister Sexton. In the meantime, the United States will need some good old Venusian know-how in order to win the Cold War. A highly sexed and violent ride, this novel blends elements of A Fistful of Dollars and The Matrix.
