Fan fiction consists of stories, poems, and other short works written by fans—not the original authors—of particular books or book series. Generally, fan fiction is written for other fans who have knowledge of the original work, whether fiction or non-fiction. Stephenie Meyer’s Twilight series has a huge fan fiction component, as does J. K. Rowling’s Harry Potter series. The Bible, too, has a large fan fiction component. As of September 2013, one of the most popular fan fiction Web sites, www.fanfiction.net, featured over three thousand derivative works based on the Bible.
