Cammie Sheppard is a girl who attends Beverly Hills High School with Anna. Cammie despises Anna and the way that her life has changed since Anna moved to town. Cammie is gorgeous, described as an "eleven" on a scale of one to ten with strawberry blonde curly hair. She uses her looks and wealth to her advantage, manipulating those around her as much as possible. Though she starts out dating Adam Flood to spite Anna and Sam, Cammie winds up developing deep feelings for Adam. At the same time, she begins to feel protective of her younger stepsister Mia, despite hating the fact that Mia has moved into the Sheppard home. As the book progresses, Cammie shows momentary emotions that convey the fact that she is really much more sensitive than her outer exterior shows.
