You've probably heard of the risque novel "50 Shades of Grey" since it's now the best selling paperback of all time. But you may not know that it's Twilight fan fiction! It seems shocking that a fan fiction novel has become so popular, but 50 Shades isn't the first book to break through the fan community boundaries into mainstream culture. Over 100 years ago, Sherlock Holmes' popularity created a profusion of well received fan fiction. It allowed authors from amateur to professional to explore the world originally created by Sir Arthur Conan Doyle, and pave the way for other future fan fiction canons, including Star Wars, Harry Potter, and yes, 50 Shades of Grey.
