In Eclipse, Bella agrees to marry Edward on the condition he will make love to her while she is still human. Edward eventually relents and agrees, on the stipulation it will only occur after they are married. The plot is driven by the machinations of the vampire Victoria, who, seeking revenge for the death of her mate James, is hunting Bella and creating new vampires to build an army. A grudging truce is made between the Cullens and the Native-American werewolf pack led by Sam Uley and Jacob Black, a friend of Bella's who was there for her when Edward broke her heart. However, the truce is endangered when Bella realizes Jacob means more to her than she thought. Ultimately, Edward accepts that Bella cares for Jacob and successfully destroys Victoria, and Bella acknowledges that Edward is the most important person in her life. Edward tells Bella that they may attempt making love before they get married, as he realizes that she spends too much of her life trying to please other people. However, she refuses his offer and agrees to doing things the way Edward initially wanted: marriage, making love, and then becoming a vampire.
Breaking Dawn sees Edward and Bella marry. Bella becomes pregnant on their honeymoon, and the rapid growth of the half-human, half-vampire fetus swiftly impacts on Bella’s health. Edward tries to coerce her into having an abortion in order to save her own life. However, Bella feels a bond with her unborn child and insists on giving birth. Edward comes to feel love for the baby as well, after he hears its thoughts and learns that the baby loves Bella in return. Bella nearly dies giving birth in an emergency c-section, but Edward successfully delivers his daughter and then injects Bella's heart with his venom, healing her wounds by turning her into an immortal vampire. During Bella's painful transformation, Jacob imprints on their baby daughter, Renesmee.
After a vampire named Irina mistakes Renesmee for an immortal vampire child—a creation forbidden in the vampire world—the Volturi arrive to destroy the Cullens. Edward stands with Bella and their allies to convince the Volturi that Renesmee is not an immortal child and poses no threat to their existence. Once the Volturi leave, Edward and Bella feel free to live their lives in peace with their daughter.
