Edward is back, but so is Victoria who is set on killing Bella as revenge for James's death. The only way to defeat her, is for the Cullen family to recruit the local werewolves to fight together.
My favorite of the Twilight series. Stephenie Meyer does a good job of letting her characters grow and develop believably. The tension between Edward and Jacob is so strong you can feel it, and Bella's dilemma is understandable. You won't be able to put this one down!
