Unauthorized 'Star Wars sequel' faces copyright reality

Three recently published science fiction novels by Chinese writer Zheng Jun have stirred up controversy with their claim to be a "sequel to Star Wars" on the book covers.

The works do not have authorization from Lucasfilm, the copyright holder of the legendary US movie series owned by creator and director George Lucas.

On his popular micro blog, author and translator Qu Chang wrote that it is "surprising the books were published".
