In "Twilight", Bella moves from Phoenix, Arizona to Forks, Washington, to live with her father. She enrolls at Forks High School (which has a population of around 300 students). There she meets the Cullens, a family of vampires. However, because they believe it is not right, they do not drink human blood – they only drink animal blood. Because of this, they call themselves "vegetarians". They are described as beautiful and extremely pale, with golden eyes that turn black when they become thirsty. They are strong and can run very fast. Their skin is ice-cold. After becoming vampires, they do not physically change anymore. They do not grow older. When in the sun, they sparkle "like thousands of tiny diamonds were embedded in the surface," according to Bella in "Twilight".
