Bella Swan move to live with her father in her birthtown of Forks, Washington. There, she becomes intrigued by a student, Edward Cullen. Edward saves her life on multiple occasions, exhibiting super-human qualities. Bella learns from family friend Jacob Black that legends say the Cullen family are vampires. Edward eventually admits to this truth, though his family hunts only animals, not humans, through moralistic choice. Edward constantly warns Bella against being with him, perceiving her life to be at risk if she continues to associate with him because the scent of her blood is so much more powerful to him than that of any other human. Bella's love and confidence in Edward's restraint is such that his warnings go unheeded, and on an outing with the Cullens she becomes the target of a sadistic vampire, James. With his family's help, Edward is able to save Bella from James' predations, but Edward is still unwilling to change Bella into a vampire herself.
Bella was upset by her 18th birthday, because it will make her "older" than the permanently 17-year-old Edward. During her birthday party Bella gets a paper cut, and his brother Jasper's instinctive hunger for Bella's blood reminds Edward of the danger their relationship puts her in. In a misguided attempt to protect Bella, he convinces her that he does not love her anymore and moves away with his family, leaving her heartbroken and depressed. To appease her worried father, Bella goes to see a film with friend, Jessica. While there, she carelessly approaches a group of men outside a bar and finds that she can hear Edward's voice when in dangerous situations. Desperate to hear his voice again, Bella seeks out danger; she asks Jacob Black to fix two motorcycles and teach her to ride one. Their friendship grows, and when the vampire Laurent decides to attack her, Bella is saved by a pack of giant wolves. Later, Bella learns that Jacob and others from his tribe are werewolves, and that the vampire Victoria wishes to kill Bella to avenge James' death. To hear Edward's voice, Bella attempts cliff-diving and nearly drowns, but she is saved by Jacob. Edward, after being mistakenly informed by Rosalie that Bella has committed suicide, travels to Volterra, Italy to ask the Volturi to destroy him. Alice returns, and she and Bella pursue and successfully stop Edward. The trio speak to the Volturi and promise to turn Bella into a vampire. The Volturi threaten to kill Bella if this promise is not kept. Upon returning home, Edward tells Bella that he never stopped loving her and wants her back, and Bella quickly accepts him. Bella is intent on becoming a vampire and decides to let Edward's family vote on her fate. All but Rosalie and Edward vote affirmatively for her to be changed, but Edward agrees to change her himself if she will marry him first.
Edward explains that he is reluctant to change Bella into a vampire because he believes that vampires are soulless creatures who have no place in heaven. Bella, whose opinion of marriage is jaded by the early divorce of her own parents, agrees to marry Edward on the condition that he will make love to her while she is still human and then turn her into a vampire. He initially refuses, saying that he could easily lose control in the heat of the moment. However, seeing how important it is to Bella, he agrees to try and make love to her while she is still human, but only after they are married. The plot is driven by the machinations of the vampire Victoria, who first met Bella and the Cullens during the first book, Twilight. Victoria, seeking revenge for the death of her mate James, the Cullens and the Native American werewolf pack led by Sam Uley and Jacob Black, who pits himself against Edward as a love interest for Bella. Initially Bella sees him only as a friend, but, despite her engagement to Edward, she later realizes that 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, agreeing to tell her father of her and Edward's engagement. Edward tells Bella that they may attempt to make love before they get married. However, she refuses his offer and says that they will do things "the right way": marriage, making love, and then becoming a vampire.
