The Venus Series by Edgar Rice Burroughs is a science fantasy series consisting of four novels and one novelette. Most of the stories were first serialized in Argosy, an American pulp magazine. It is sometimes known as the Carson Napier of Venus Series, after their fictional main character, Carson Napier. Carson attempted a solo voyage to Mars, but, because of mistaken navigational calculations, he finds himself heading toward the planet Venus instead. The novels, part of the Sword and Planet subgenre of science fiction, follow earthman Napier's fantastic adventures after he crash-lands on Venus, called Amtor by its human-like inhabitants. Unlike Barsoom, the desert planet of Mars, these stories are set upon a waterworld. Most of the events of the series take place on the island of Vepaja, the kingdom of Korva on the island of Anlap, and the city-states of Havatoo and Kormor on the tropical continent north of Vepaja.
