Answer:
She says that is is "indefinitely postponed" (it may never be done). She plans to continue writing it, though. But not soon... It could be out sometime this year.
She said she is really depressed about how one of her good friends went behind her back and put it all over the internet so she is taking a break so she can get in a healthier state of mind so she wont have James win and the Cullens die. So the question is still up in the air. If she does decide to follow through, it will be a while until it is published (writing it and all). So just be pateint and hope for the best!
I think the Midnight sun is already being printed rite now and going in stores!!!!! And i am a really big fan of twilight i mean iv read the series about 20 times and im stilll in love with it so. Also seen the movie about 7 times already and still love that.

Midnight sun will most likely not be published because of one of her clients/friends' going behind her back and posting her prelude au midnight sun all over the internet, heres a URL to get to her prelude au midnight sun that she posted herself

Midnight sun
Heres what we will do, we will change it to make it even more better then the whole twilight series combined, and then, when we are rich as heck,we will rub the money in stephys face.
that is what they probably think.and this is what SHOULD happen.
==they go to jail, and Stephanie Meyer will prevail over her distraught emotions, and give US FANS ONE MORE book in the twilight series and then she will be done, and life will go on. YAY!!!!! life as we all know it will be better because of justice and whatnot being done.
It hasent been decided yet but there is a possibility and you spelt her name wrong.</zzz>
