After Bella's marriage with Edward, they spend their honeymoon on Isle Esme, a private island off the coast of
Brazil that Carlisle owns. Two weeks into their honeymoon, Edward and Bella have sex for the first time, and Bella becomes pregnant. Because the fetus is part-vampire, her pregnancy progresses at an accelerated rate, causing Bella severe physical and emotional distress. Bella and Edward return home to
Forks, Washington. Knowing of Bella's wish to become a vampire, Jacob is suspicious when she returns from her honeymoon and the Cullens keep her father, Charlie, from seeing her. Believing the Cullens broke their treaty not to bite another human, he advances on their home intending to kill Edward. Jacob visits the Cullen residence and seeing the state Bella is in due to her pregnancy, begs Bella to
abort the fetus to save her own life, as neither Carlisle, a doctor, nor Alice who can see the future, are optimistic about Bella's prognosis. Despite concerns that her pregnancy will be fatal, Bella refuses to terminate it, believing she can survive long enough to give birth and then be transformed into a
vampire. As the wolves are telepathic, they hear Jacob's thoughts about Bella. Fearing Bella will give birth to an uncontrollable, bloodthirsty child, they decide to kill her and the fetus. Jacob accepts his bloodline as the true pack leader to break free from the alpha, Sam's control. He goes to warn the Cullens that the wolf pack plans to kill Bella. En route, Seth Clearwater, a younger pack member, also breaks away and joins Jacob. Having formed their own pack, the two discover they can no longer hear the other wolves' thoughts. They begin patrolling the Cullens' property before Leah, Seth's older sister and the lone female wolf, joins them. Bella goes into labor and the baby begins fighting its way out of her body, inflicting life threatening injuries on Bella. In an attempt to save Bella's life Edward performs an emergency cesarean section. As Bella is dying, Edward injects his venom into her heart. Jacob, believing Bella is dead, blames her baby,
Renesmee. He goes to kill Renesmee but instead
imprints (an involuntary response in which a shape-shifter finds his soul mate) on her. After her painful transformation, Bella wakes to find herself changed into a vampire. Fully recovered, she enjoys her new life and vampire abilities. Renesmee grows rapidly into a toddler and is spotted at a distance by Irina, a vampire from the Alaskan coven. Misidentifying her as an "immortal child," a human child who is turned into an uncontrollable vampire, Irina presents her allegations to the Volturi who outlawed the creation of such creatures. As the largest and most powerful vampire coven, the Volturi see Renesmee and the Cullens as a threat and plot to destroy them. Foreseeing their arrival, the Cullens gather other vampire clans from around the world to stand as witnesses and prove that Renesmee is not an immortal child upon Alice's request. Jacob's imprinting on Renesmee forged an unbreakable bond and mutual protective pact between the Cullens and the Quileute, ending the hatred between them. As local and foreign vampires arrive, the Cullen house becomes the headquarters and training ground for the assorted vampires and the Quileute wolf packs. Bella learns that she is a 'shield', meaning the gifts of other vampires do not work on her, which is why Edward and Aro cannot read her mind. Bella works with the other vampires to improve her skill and shield people other than herself. Upon confronting the gathered Cullen allies and witnesses, the Volturi discover that they were misinformed on Renesmee's identity. The Volturi execute Irina in an attempt to instigate a full battle but are unsuccessful. They bring up the Cullens' pact with the Quileute wolves and the uncertainty of Renesmee's future in an effort to further provoke hostilities, naming her as a threat to the secret existence of vampires. Alice and Jasper, who left prior to the gathering of the Cullen's allies, return with a
Mapuche called Nahuel, a 150-year-old
vampire-human hybrid like Renesmee. Alongside him is his biological aunt, Huilen, who explains that her sister fell in love with a vampire and became pregnant with his child, but died in childbirth. When Nahuel was born, he bit Huilen, turning her into a vampire. With Nahuel having proved that hybrids pose no threat to the existence of vampires, the Volturi agree to leave the Cullens alone. The Cullens and their allies leave in peace, realizing that the Volturi may one day return. While alone with Edward, Bella lowers her mental shield, allowing Edward to read her mind for the first time, sharing her thoughts and feelings for him. ==Background==
