If you don't know what that is, let me explain briefly;

Fan fiction is exactly what it sounds liek. It's when somebody likes a book/tv show/ movie/ etc, and writes a continuation. Its like writing a story based off of another story. For example;
Vampire Academy.
For this fan fiction, you would continue on the book. It could be from in the middle, or at the end or a pre-story. You could write what happened to Rose & Lissa before they were taken back to the academy. You could write about Rose going after Dimitri. You could expand on Rose & Mason's relationship when they were alive.

Andy fan fiction you want can be posted here. {So long as its VA related}
