James Cameron has announced plans for a series of Avatar spin-off books.
The director has signed up Jumper author Steven Gould to write four stand-alone novels, set in the fictional universe Cameron created for his Oscar-winning film, according to The Hollywood Reporter.
Cameron said: "Steven Gould is one of the shining lights in contemporary science fiction. I've long admired the worlds and characters he's created in his books and stories. We're very fortunate to have Steven bring his formidable talents to the Avatar universe. He is already working closely with me and the screenwriters to flesh out the expanding world of Avatar."
Cameron recently announced he will make a fourth Avatar film, after finishing his work writing the sequels.
He plans to shoot all the sequels at the same time, starting next year.
Avatar 2 is set to be released in December 2016.
