Isabella Swan, 17, had never experienced great emotions in her life. Being an extremely responsible, shy and introspective young woman, she decides to move from the sunny city of Phoenix, where she lived with her mother (Renée) and her new husband (Phill), due to her apprehensive state, to the small and rainy city from Forks (although I hate it), where she would live with her father, Charlie, the head of the local police.
On the first day of classes at her new school, Bella, as she liked to be treated, comes across five young people of superhuman beauty in the cafeteria: Edward, Alice and Emmett Cullen, Rosalie and Jasper Hale.
Later, in Biology class, she meets Edward Cullen, who seems deeply irritated by her presence, and who even tries to change her class schedule so as not to have to live with her, besides, after being almost run over, being saved by Edward, taken to the hospital, and met the head of the family Carlisle Cullen.
