I am exceedingly happy my sister, my good friend, and a gaggle of my students "forced" me to read all four books in the Twilight series. I can say that I do not regret it.
Breaking Dawn was pretty fantastic. It is a long book-- over seven hundred pages!-- but the pace is quick, and it read faster than I expected. I found myself trying to imagine the scenes described so well by Stephenie Meyer, trying to imagine how these scenes would manifest in the movie version of the series' finale (which I am told is not necessarily going to happen!). Of all the books, this one was, I think, the most imaginative and, thus, interesting.
However, I still prefer New Moon. There is something real about the series' second installment that I connect to more emotionally, and an emotionally powerful story always makes a bigger impact on me than one that is action-packed or fantastic.
All that said, the Twilight series is one not only to enjoy, but also one to re-read and re-imagine. I just hope they decide to butcher the series and squeeze into two hours of movie-watching.
Below is my preference of the novels. I have yet to meet anyone who can agree on the order of greatness. Post a comment with your own order. Let's see if we can reach a consensus (or just have a light-hearted debate).
1. New Moon
2. Breaking Dawn
3. Eclipse
4. Twilight
Happy reading!
