Isabella "Bella" Swan moves from sunny Phoenix, Arizona to rainy Forks, Washington to live with her father, Charlie, while her mother, Renée, travels with her new husband, Phil Dwyer, a minor league baseball player. Bella attracts much attention at her new school and is quickly befriended by several students. Much to her dismay, several boys compete for shy Bella's attention.

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. Seemingly defying the laws of physics, Edward saves her life when he instantaneously appears next to her and stops the van with his bare hands.

Bella becomes hellbent on figuring out how Edward saved her life, and constantly pesters him with questions. After tricking a family friend, Jacob Black, into telling her 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 so desirable to him. Over time, Edward and Bella fall in love.

Their relationship is thrown into chaos when another vampire coven sweeps into 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 he is holding her mother captive. When Bella surrenders herself, James attacks her, but Edward, along with the other Cullens, rescues Bella and destroys James. Once they realize that James has bitten Bella's hand, Edward sucks the venom from her system before it can spread and transform her into a vampire, and she is then sent to a hospital. Upon returning to Forks, Bella and Edward attend their school prom and Bella expresses her desire to become a vampire, which Edward refuses.
