Why are the vitabu called Twilight?

From Stephenie's website:
'Why did wewe pick the title Twilight?

Twilight was not the easiest book to title. When I started sending out queries, I called it Forks for lack of a better idea. The first thing my agent advised me was that the title was going to have to change. We played around with a lot of different titles, and nothing seemed to convey the right feel. We brainstormed through emails for about a week. The word twilight was on a orodha of "words with atmosphere" that I sent her. Though these words were meant to be used in combination with something else, the word twilight stood out to both of us. We decided to try it out, and, after a little adjustment time, it started to work for both of us. It isn't absolutely perfect; to be honest, I don't think there is a perfect title for this book (or if there is, I've never heard it). When I look at the titles other countries have used (examples: Germany: Bis zum Morgengrauen which is "Until Dawn" au "Bite" if wewe add an "s" to make it "biss" (if wewe look at the German book cover on the Twilight International page); Finland: "Temptation;" France: "Fascination;" and Japan, which has mgawanyiko, baidisha it into three separate books: "The Boy Whom I upendo is a Vampire," "Blood Tastes Sadness," and "The Vampire Family in the Darkness."), it seems like I might be right about that. (Both New Moon and Eclipse were much easier to title, and the titles also fit better.)'


So urm yeah, I don't really know. xD

Humorous Answer: Because "The Sparkley Adventures of Count Fagula and Mary-Sue" didn't make the cut.

Serious Answer: I think it had something to do with the word "twilight" being mentioned in the book. Same with New Moon, Eclipse, Breaking Dawn, and Midnight Sun.

I honestly don't know why the vitabu are called twilight. I think it's not really connected to the story that much.. I guess because it sounds...cool au um... mysterious au some other stuff like that :))
