Isabella "Bella" Marie Swan (later Bella Cullen) is a clumsy, accident-prone teenage girl who moves from Phoenix, Arizona, to Forks, Washington, to live with her father, Charlie. Though many boys are attracted to her when she arrives, she falls in love with Edward Cullen, a mysterious boy she discovers to be a vampire. In an attempt to protect Bella, Edward leaves her. Bella falls into a depression and is comforted by her friend, Jacob Black. She comes to love Jacob as well, though not as deeply as she loves Edward. She eventually marries Edward and, after a complicated pregnancy, gives birth to their daughter, Renesmee, and becomes a vampire at age 18. After Bella's transformation, she has the ability to shield her and others' minds from mental attacks
Bella Soulmate: Edward Cullen
When Bella is seated next to Edward Cullen in class on her first day of school, Edward seems utterly repulsed by her. He disappears for a few days, but warms up to Bella upon his return; their newfound relationship reaches a climax when Bella is nearly run over by a fellow classmate's van in the school parking lot. Edward saves her life when he instantaneously appears next to her and stops the van with his bare hands.
Bella becomes determined to find out how Edward saved her life, and constantly pesters him with questions. After a family friend, Jacob Black, tells her the local tribal legends, Bella concludes that Edward and his family are vampires who drink animal blood rather than human. Edward confesses that he initially avoided Bella because the scent of her blood was too desirable to him. Over time, Edward and Bella fall in love.
Their relationship is disturbed when another vampire coven arrives in Forks. James, a tracker vampire who is intrigued by the Cullens' relationship with a human, wants to hunt Bella for sport. The Cullens attempt to distract the tracker by splitting up Bella and Edward, and Bella is sent to hide in a hotel in Phoenix. There, Bella receives a phone call from James, who claims to be holding her mother captive. When Bella surrenders herself, James attacks her. Before she is killed, Edward, along with the other Cullens, rescues her and defeats James. Once they realize that James has bitten Bella's hand, Edward successfully sucks the poison from her bloodstream and prevents her from becoming a vampire, after which she is brought to a hospital. Upon returning to Forks, Bella and Edward attend their school prom and Bella expresses her desire to become a vampire, but Edward refuses.

Bella Becomes a vampire:
Near the beginning of Breaking Dawn, Bella marries Edward. They spend their honeymoon on Isle Esme, a fictional small island that was given to Esme as a gift from Carlisle. They consummate their marriage, but their lovemaking sparks a conflict between the newlywed couple: Edward is horrified that he has bruised his wife, but Bella insists that she is fine and wants Edward to make love to her again. He vows not to do so again while she is still human, but he eventually gives in. Soon afterwards, Bella becomes very sick and realizes that she is pregnant with Edward's child.
Edward is shocked and rushes Bella home to see Carlisle, who, as a doctor, confirms that she is expecting a child. Edward goes half-crazy with worry as the rapidly growing fetus begins to drain Bella's health, and he tries to coerce her into having an abortion to save her own life. However, Bella feels a bond with her unborn child and insists on giving birth. Soon, Edward comes to love the baby as well, after he hears its thoughts and learns that the baby loves Bella in return and doesn't mean to hurt her.
Bella nearly dies giving birth, but Edward successfully delivers their baby girl and then injects his venom into her heart, thus healing her wounds by turning her into a vampire. During Bella's painful transformation, Jacob imprints —an involuntary process in which a werewolf finds his soul mate— on the baby, Renesmee Cullen.
After a vampire named Irina mistakes Renesmee for an immortal vampire child (a creation that is forbidden in the vampire world), the Volturi arrive to destroy the Cullens as punishment for the alleged transgression. 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 are finally free to live their lives in peace with their daughter
