Twilight (twilight 1) by Stephanie Meyer

Summary: Headstrong, sun-loving, 17-year-old Bella declines her mom's invitation to move to Florida, and instead reluctantly opts to move to her dad's cabin in the dreary, rainy town of Forks, WA. She becomes intrigued with Edward Cullen, a distant, stylish, and disarmingly handsome senior, who is also a vampire. When he reveals that his specific clan hunts wildlife instead of humans, Bella deduces that she is safe from his blood-sucking instincts and therefore free to fall hopelessly in love with him. The feeling is mutual, and the resulting volatile romance smolders as they attempt to hide Edward's identity from her family and the rest of the school. Bella and Edward's struggle to make their relationship work becomes a struggle for survival, especially when vampires from an outside clan infiltrate the Cullen territory and head straight for her.
