Midnight Sun is Twilight,but from Edward's POV.Unfortunately it is unfinished and also not published.I do not know if or when Stephenie Meyer will finish writing it and possibly publishing it,but I do hope she does.
It's the events of the first Twilight book written from Edward's POV. Stephenie Meyer began it, but when she gave some chapters to a supposed friend to proof read who then published it online without her consent, she felt so betrayed that she stopped. She's said that she'd considered continuing it a few times - the latest was for the 10 year anniversary of the series - but so far there's always been something making her stop.
