She never detto anything about her Scrivere all four books. What she ACTUALLY detto was, "I think it is important for everybody to understand that what happened was a huge violation of my rights as an author, not to mention me as a human being...This has been a very upsetting experience for me, but I hope it will at least leave my fan with a better understanding of copyright and the importance of artistic control. So where does this leave Midnight Sun? My first feeling was that there was no way to continue. Scrivere isn't like math; in math, two plus two always equals four no matter what your mood is like. With writing, the way te feel changes everything. 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.

So people should really just stop and fully read what she said, that way there won't be a bunch of false information being spread around.
