I have read the entire Twilight series. Twilight and New Moon are my favorites, Eclipse is okay, but in my opinion, Breaking Dawn is a bit of a letdown. In Breaking Dawn, Bella and Edward get married, go on a honeymoon, and Bella gets pregnant. I think that the book focuses too much on the vampire baby. The entire book is about it!
The whole book is about the abnormalities of the baby, and how the Cullens must protect it.
