}}

Much to her mother's dismay, Kirsten has put on thirty pounds in three months. Kirsten feels the weight of her mother's disapproval and sees it mirrored in her friend troubles at school. Best friend Rory has abandoned her less-than-fashionable friend for Brianna, the school's spoilt princess. Kirsten is lonely and ready to sacrifice almost anything to join the in group too, but her conscience is a tiny but insistent voice inside that sees Brianna's group for the unpleasant, cruel clique that it is.
