Here is the article I read about it or you can get on stepheniemeyer.com and read her statement and also the portion that she released for the public.
*************************************************************************************
In a note posted to her official website Thursday, author Stephenie Meyer tells her readers she has decided to discontinue "Midnight Sun," her planned retelling of "Twilight" from the teenage vampire Edward's perspective, after an unfinished draft was illegally posted and distributed on the Internet without her knowledge or permission.
If I tried to write "Midnight Sun" now, in my current frame of mind, James would probably win and all the Cullens would die, which wouldn't dovetail too well with the original story. In any case, I feel too sad about what has happened to continue working on "Midnight Sun," and so it is on hold indefinitely.
Meyer had originally made the only first chapter available on her site. Because the project is now virtually killed, she's made the incomplete draft available as well, but cautions that "the writing is messy and flawed and full of mistakes."
I rather my fans not read this version.... It was only an incomplete draft.... But to end the confusion, I've decided to make the draft available.... I hope this fragment gives you further insight into Edward's head and adds a new dimension to the Twilight story. That's what inspired me to write it in the first place.
This has been a roller-coaster year for Meyer, who just completed a successful concert book series but has also had to answer for some of the backlash directed at "Breaking Dawn," the fourth and final installment of the "Twilight" saga.
