Fanfiction is a word that is being bandied about more and more in the publishing industry. But what is it exactly? Fanfiction is basically writing a book in another author’s “world.” You use some of their characters and locations and weave them into your own story. Of course you can’t just write this kind of story and publish it on your own, without the approval and blessing from the original author (you don’t want to be accused of plagiarism or “stealing” another author’s ideas and characters). So how does fanfiction work?
