Two weeks into their honeymoon, Bella realizes that she is pregnant and that her condition is progressing at an unnaturally accelerated rate. After contacting Carlisle, who confirms her pregnancy, she and Edward immediately return accueil to Forks, Washington. Edward, concerned for Bella's life and convinced that the fetus is a monster as it continues to develop with unnatural rapidity, urges her to have an abortion. However, Bella feels a pull towards the child and refuses to go through with the procedure.
The seconde part of the novel is written from the perspective of werewolf Jacob Black, and lasts throughout Bella's pregnancy and childbirth. Jacob's Quileute werewolf pack, not knowing what danger the unborn child may pose, make plans to destroy it, even though they must kill Bella to do so. Jacob vehemently protests this decision and leaves, forming his own pack with Leah and Seth Clearwater. Bella soon gives birth, but the baby breaks many of her Bones and she loses massive amounts of blood. In order to save her life, Edward changes her into a vampire par injecting his venom into her heart. Jacob, who was present for the birth, almost immediately "imprints"—an involuntary response in which a werewolf finds his soul mate—on Edward and Bella's newborn daughter, Renesmee.
The third section of Breaking Dawn shifts back to Bella's perspective, finding her changed into a vampire and enjoying her new life and abilities. However, the vampire Irina misidentifies Renesmee as an "immortal child", a child who has been turned into a vampire. Because "immortal children" are uncontrollable, creating them has been outlawed par the Volturi. After Irina presents her allegation to the Volturi, they plan to destroy Renesmee and the Cullens. In an attempt to survive, the Cullens gather other vampire clans from around the world to stand as witnesses and prove to the Volturi that Renesmee is not an immortal child. Upon confronting the gathered Cullen allies and witnesses, the Volturi discover that they have been misinformed and immediately execute Irina for her mistake. However, they remain undecided on whether Renesmee should be viewed as a threat to vampires' secret existence. At that time, Alice and Jasper, who had left prior to the confrontation, return with a Mapuche called Nahuel, a 150-year-old vampire-human crossbreed like Renesmee. He demonstrates that the crossbreeds pose no threat, and the Volturi surrender. Edward, Bella and Renesmee return to their accueil in peace.

I got this from wikipedia and I hope they make this movie soon, because I've heard they have already finished Eclipse but are just waiting to put it in theatres in 2010, so I hope they finish this movie soon so the saga will be complete! ;D
