New Moon: Karen held a birthday party for Bella at her home. Everything was fine, but because Bella accidentally cut her finger on the wrapping paper when opening the gift, Jasper couldn't resist the temptation to drink Bella's blood. This incident dealt a great blow to Edward. He thought that he and his family would pose a threat to Bella's safety, so he lied to Bella that he no longer loved her and left her. After Edward left, Bella felt desperate and lived like a walking corpse until she met her former friend Jacob. Bella and Jacob feel relaxed together. They don't seem so sad anymore. At the same time, when Bella met Lauren (the vampire with Victoria and James in the first film), she found that when she was in crisis, she could see Edward's vision, so she began to be keen on some dangerous activities. After the Cold War, she discovered Jacob's secret: he was a werewolf (the natural enemy of vampires). Bella didn't dislike Jacob because he was a werewolf. Their friendship grew deeper and deeper, and gradually developed into ambiguity. At the same time, Bella found that Victoria had been looking for opportunities to commit suicide in revenge for James's murder by Edward. But because of the protection of wolves, Bella has always been safe. Meanwhile, Bella is still thinking about Edward. She wanted to see Edward's vision again, so she decided to jump off the cliff and was rescued by Jacob. But Alice thinks Bella committed suicide because she can't foresee the future of werewolves. After telling Rosalie, she hurried back. After discovering that Bella was all right, she decided to stay with her for a few days because of Bella's pleading. But Rosalie told Edward the wrong message because she didn't like Bella. Edward called Bella's house to confirm that Jacob answered the phone, which made Edward misunderstand that Bella really committed suicide. Edward couldn't stand living without Bella, so he went to Italy and asked Volturi (the vampire royal family) to sentence himself to death. Volturi refused Edward's request because he wanted to attract him with his strange power. So Edward decided to expose his vampire identity in order to get the death penalty. Alice foresaw Edward's idea and went to Italy with Bella to stop Edward. Bella rushed into Edward's arms at the last second to prove that she was still alive. But Volturi didn't let them go and brought them back. Because of the existence of Jane (the first warrior in Volturi who can make his opponent feel miserable with his will), Edward and Alice gave in without fighting back and were taken to the underground palace in Volturi with Bella. Arrow (one of the three leaders in Volturi) appreciates Edward's mind reading, Alice's foresight and Bella's defense (Jane's super powers don't work on Bella). After Alice promised that Bella would become a vampire and would not reveal the secret that vampires still exist because of her human identity, Volturi let them go. The three of them returned to Fox unscathed, but because of this, Edward knew that he and Bella could not live without each other. In addition, this accident completely freed Edward from his thirst for Bella's blood, and Edward decided to stay with Bella. Finally, the Cullens voted that Bella would become a vampire (Edward disagreed), but she would not change until she graduated from high school. Jacob and Edward love Bella deeply. Bella can't lose Edward, but she doesn't want to lose Jacob, a close friend. Jacob couldn't accept Bella becoming a vampire, so their emotional entanglement deepened.
In Eclipse, Bella and Edward still live happily together, interspersed with small fights from time to time: Edward is dissatisfied with Bella's insistence on becoming a vampire; Bella is not happy that Edward doesn't allow herself to meet Jacob (the transformation of a werewolf is greatly influenced by emotions, so Edward thinks it is dangerous to get close to a werewolf). But after some arguments, the two reached an agreement: Bella can see Jacob, but she should keep in touch with Edward at any time; After Bella accepts Edward's proposal, Edward can change Bella at any time. The contradiction between the three seems to have been solved, but it is not: Edward and Jacob love Bella wholeheartedly, and Bella insists that she loves Edward deeply and does not want to hurt Jacob at the same time. As early as n years ago, there was an agreement between werewolves and vampires: the Cullens should not bite any human, otherwise, werewolves and vampires would go to war. This also makes it difficult for Bella to become a vampire. At the same time, Victoria organized an army of about 20 newborn vampires to go to Fox to kill Bella. With the cooperation of the Cullen family and the werewolf, Victoria and the newborn vampire were eliminated. In this process, Jacob wants to fight to the death because he can't get Bella's feelings. Bella must kiss him to make sure that she still has deep feelings for him. The entanglement of the three reached a climax. Victoria's attack alarmed Volturi, and Jane came to see it with her hands, dissatisfied that Bella had not become a vampire. Finally, Bella and Edward got engaged, and Jacob couldn't stand the blow and ran away from home.
Dawn: Edward and Bella got married, and Jacob returned to Fox in time to attend the wedding, giving Bella a surprise. But when she learned that Bella was going to become a vampire after the wedding, she almost hurt Bella because she lost control of her emotions. Bella felt sorry for Jacob's sadness. After the wedding, Bella and Edward went to Esme (a gift from Carlisle) for their honeymoon. They lived a very happy life, but at the end of their honeymoon, they found out that Bella was pregnant. So they soon returned to Fox. Carlisle found that having a half-vampire fetus had a great influence on Bella's body, so that Bella was always in a very haggard state. Edward and Carlisle advocated aborting the baby, but Bella and Rosalie disagreed. During this time, Rosalie often accompanied Bella to protect the safety of the fetus, and their relationship improved. Jacob learned about Bella and came to visit her. Bella thinks Jacob is good around. After a short pregnancy (the vampire fetus grows very fast), Bella gives birth. The production process almost killed Bella. When Bella was dying, Edward changed Bella and Bella became a vampire. On the other hand, Jacob fell in love with Bella's daughter, Renis May, at first sight because of the werewolf's fate (the brand of love-werewolf lovers are destined to feel an extraordinary attraction as long as they want to see each other). With the help of Edward and the Cullens, Bella began to learn to adapt to the life of vampires. Meanwhile, Bella meets Charlie. Charlie felt Bella's obvious change, but when he learned that his friend's son Jacob was actually a werewolf, he refused to listen to Bella's explanation. So, Bella didn't reveal the secret of vampire existence, and she didn't lose Charlie. She still maintains a close relationship with Charlie, and she takes Renis May back from time to time to have a look. As for the agreement between the werewolf and the vampire, because of the tradition of the werewolf-no one can hurt the branded lovers of other werewolves, it has been successfully solved. As a half-human, half-vampire hybrid, Renes May has both human and vampire characteristics, but Edward and Bella are still worried about the rapid growth of Renes May. She only has ten years to live. At the same time, Volturi learned of the existence of Renis May and mistakenly thought that Renis May was a vampire's child (vampire's children were forbidden because of their lack of self-control over blood), so Volturi decided to go all out to take this opportunity to annihilate the Cullen family. Alice foresaw the war, and the Cullens joined forces with dozens of vampires to resist. Coupled with Bella's powerful defense ability after becoming a vampire, they added weight in the war with Volturi. Finally, Alice and Jasper brought back evidence that being half-human and half-vampire is not dangerous, so that the war can be ended. Volturi had to go home empty-handed. Bella finally put down her worries about her daughter's premature death after learning from Alice that half-human and half-vampire also have eternal life. At the end of the story, Edward lives happily with Bella, Jacob and Renis May.
Midnight Sunshine: The author retells the whole story of Twilight from Edward's perspective, which is interspersed with a lot of Edward's psychological description and the daily life of the Cullens. However, due to the massive leakage of the manuscript, Mel was very angry and she stopped writing. So the midnight sunshine is not complete, only about a quarter of the light.
