Isabella "Bella" Swan moves from sunny Phoenix, Arizona, to rainy Forks, Washington, to live with her father, Charlie. She chooses to do this so that her mother, Renée, can travel with her new husband, Phil Dwyer, who is a minor league baseball player. In Phoenix she was a bit of an outcast, so it surprises her that she attracts much attention at her new school, and is quickly befriended by several students. Much to her dismay, several boys in the school compete for shy Bella's attention.
When Bella sits next to Edward Cullen in class on her first day of school, Edward seems utterly repulsed by her. He even attempts to change his schedule to avoid her, leaving Bella completely puzzled about his attitude towards her. After tricking a family friend, Jacob Black, into telling her the local tribal legends, Bella concludes that Edward and his family are vampires. Although she was inexplicably attracted to him even when she thought Edward drank human blood, she is much relieved to learn that the Cullens choose to abstain from drinking human blood, and drink animal blood instead. Edward reveals that he initially avoided Bella because the scent of her blood was so desirable. Over time, Edward and Bella fall in love.
The seemingly perfect state of their relationship is thrown into chaos when another vampire coven sweeps into Forks, and James, a tracker vampire, decides that he wants to hunt Bella for sport. The Cullens plan to distract the tracker by splitting up Bella and Edward, and Bella is sent to hide in a hotel in Phoenix. Bella then gets a phone call from James in which he says that he has her mother, and Bella must give herself up to James at her old dance studio, to save her. She does so, and while at the dance studio, James attacks her. Edward, along with the rest of the Cullen family, rescue Bella before James can kill her. Once they realize that James has bitten Bella's hand, Edward sucks the venom out of her system before it can spread...
