I can't believe that I just barely found out about this yesterday, but Stephenie Meyer is working on another book that coincides with the Twilight series. It's called Midnight Sun and it's basically Twilight but from Edward's point of view. She has the first chapter posted on her website and it's great! I'm so excited to read the whole thing! It sounds like it may take a while before reaching publication, but I am still super anxious! So for any of you who have read the series, you will thoroughly enjoy this! Just check it out at http://stepheniemeyer.com/midnightsun.html
I don't think you'll be disappointed!
