"As August 13th draws closer, Bella is more sure than ever that she has made the right choice - forsaking her human life to spend eternity with Edward. But a new enemy stalks closer, seeking to tear Bella and Edward apart forever, one with ties to both Vampire and Werewolf.
Can the treaty between the two hold?
Or will the new threat force both sides to settle their blood feud once and for all?
Because when the dawn breaks an angel will fall."

(I think the villian is Van Helsing XD!)
