30 Published Fanfictions

Here's a list of published fanfiction...books and or musicals/plays that either started out as fanfiction or are clearly fanfiction and got published, because they fall under a legal loop-hole. (ie. the original work is in the public domain or, it's vaguely based on the original work but in reality bares little resemblance to it. Everybody's Human fic for Spike and Buffy and other genres probably fits here.)

1. Fifty Shades of Grey - based on a Twilight fanfic ( not as bad as everyone thinks and yes, this is coming from someone who thinks Twilight is unreadable tripe and was wildly critical of Fifty Shades and thought it ludicrous that it was doing so well...but, I had to take two steps back, and well has anyone looked at the novels on the best-seller list lately. )

2. Pride & Prejudice and Zombies (god this one was bad, I picked it up in book store, unreadable tripe. And a blatant attempt to use someone else's work to make money. If Austen was alive? She should sue for plagirism.)
3. Sense and Sensability and Sea Monsters (stop the madness please)
4. Ahab's Wife - won an award
5. The Wide Sargasso Sea - about Mr. Rochester's first wife in Jane Eyre
6. Death Comes to Pemberly by PD James - I hear it is deathly dull
7. Scarlett - the sequel to Gone with the Wind (not very good I hear)
8. Jane Smiley's A Thousand Acres (a modern version of King Lear)
9. Alice Hoffman's Here on Earth - a modern version of Wuthering Heights
10. Geraldine Brooks - March - a parallel re-telling of Little Women
11. JM Corteze's novel - Foe based on Robinson Crusoe
12. Stephen Moffat's Sherlock and Jekyll - fanfic series based on Sherlock Holmes and Dr. Jekyll and Mr. Hyde
13. My Fair Lady - a rip-off musical version of George Bernard Shaw's Pgymallion
14. West Side Story - a rip off of Romeo and Juliet
15. Bridget Jones Diary - a modern day retelling of Pride and Prejudice
