I don't think that Stephanie Meyer has written it yet. I wish that she had :(
The Twilight Saga consists of the following books: "Twilight," "New Moon," "Eclipse," "Breaking Dawn," and "Midnight Sun."
I think that she is going to finish writing it after Breaking Dawn Part 2 comes out!
The ISBN of Midnight Sun - graphic novel - is 978-1-59362-088-2.
It's called Midnight Sun. If you don't want to wait for the book to come out or buy it when it does, you can read it online. Now (before Midnight Sun is released) you can only read the first 12 chapters but you will be able to read it when it comes out (full version).
Alaskan - 2010 The Yukon Midnight Sun 2-7 was released on: USA: 25 February 2012
Northern Exposure - 1990 Midnight Sun 4-2 is rated/received certificates of: Canada:14A (video rating)
On Stephenie Meyer's official site, there is a page called "Twilight Series" if you click on that you will find Midnight Sun. Once there you look at the bottom of her little note "Midnight Sun partial draft" there are about 260 pages written.
As she said in Midnight Sun it varies from Vamp to Vamp. In Midnight Sun we find out that Jasper finds it harder than the rest after about 2 weeks
Alaska State Troopers - 2009 Crime Under the Midnight Sun 2-8 was released on: USA: 27 February 2011
It's not necessary to read the entire Twilight saga before reading Midnight Sun. However, having some familiarity with the characters and events from the original series may enhance your understanding and enjoyment of Midnight Sun.
probably not, unless if all the movies do really well, who knows, lets see if midnight sun even comes out yet
she said in an interview it will be in around 2 years until everyones forgotten about it :(
