The Twilight series has some of the most shocking and appalling writing I have ever had the misfortune to read - except maybe for Christopher Paolini and his Inheritance Cycle. But for Twilight, the horrible prose actually suits it. The Twilight books are in the first-person perspective of Bella, who is a high school teenage girl. And the prose works, because it looks like it's been written by a high school teenage girl (no offense to you teenage girls who are competent writers). The bad prose adds to Bella's perspective.

Although this does not save the book from it's turgid plot and empty characterization.
