Stephenie Meyer's four-book Twilight series has an unofficial and lesser-known companion novel, Midnight Sun, which retells the story of the first novel Twilight from Edward's point of view instead of Bella's. Meyer never completed this book, but a draft version was leaked on the internet and has since been made freely available on Meyer's website. According to Wikipedia, the reason Meyer never finished this project was due to her own change of heart about the story:
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.
It's unclear from this quote exactly how and why Meyer's attitude changed, but clear that it did. Authorial intent aside, however, I'm curious about how, if at all, this change in attitude comes across in the actual text - whether it could be guessed or deduced at all from a close reading.
Are there differences in tone between Twilight and (the published part of) Midnight Sun which correspond to the author's change of heart about the story?
In other words, does the text of Midnight Sun differ in its portrayal of the Cullens, or any other characters, from the text of Twilight?
