Fan Fic's that I think you must read, Laura Luann's recommendations are (drum roll please):
Emancipation Proclamation
EP is heart stopping beautiful and I recommend it to everyone, it is my number one favorite fan fiction. It features a Mobward and a Slavella, turned Freella, I love it. Bring your tissues, because you will cry and set aside a few days, because it is a good 70+ chapters long.
Just Wait
JW has a troubled Bella and a very awkward Edward, but the way she writes is so different and so captivating, it is also a must read.
Day Break
It is a rewrite of the Twilight Saga, Bella never made it into the school on the first day, she was hit by Tyler's van put into a comma. She wakes up to find that she dreamed the entire story of the Twilight books, but she thinks they are real. (That may not of made much sense, but I promise it is different and good)
The Cannabean Betrothal
This is a very different story and I don't even know where to start to summerize it, but basically Bella is Cannabean (I think, lol), it is almost like Amish, anyway and Edward is also, but he spent some time not following the rules. (he rebelled) Anyway, follow them through the Cannabean Betrothal, it is different, new, and very interesting.
The Fallout
This is her summary, because I couldn't think of how to summerize it,
March 16/06 the world the Cullens knew ended. Faith, hope & love are powerful things. Edward is about to find out how powerful they are. Yes,set during a post-apocalyptic nuclear war. Try the Prologue before passing judgment. You might be surprised! NM/AU
I Run to You
One word: AMAZING
I absolutely love it, go read it now!
I will add more later, because trust me there are more. LOL
