Witch World is a speculative fiction project of American writer Andre Norton, inaugurated by her 1963 novel Witch World and continuing more than four decades. Beginning in the mid-1980s, when she was about 75 years old, Norton recruited other writers to the project, and some books were published only after her death in 2005. The Witch World is a planet in a parallel universe where magic long ago superseded science; early in the fictional history, it is performed exclusively by women. The series began as a hybrid of science fiction and sword and sorcery, but for the most part it combines the latter with high fantasy.
