Lara, 16, is just what most girls want to be: thin, beautiful, and smart. She's dating one of the cutest boys in school, and she's popular. Then she notices that she's gained a few pounds. Unconcerned, she starts to work out harder and watches what she eats. However, her weight keeps going up, and soon Lara weighs over 200 pounds. She spends a week in a hospital on a controlled liquid diet, and the doctors and nutritionists can't understand why she becomes even heavier. Suddenly, she is no longer popular and is faced with ridicule from everyone around her. The story of Lara's weight gain is set against a backdrop of her outwardly perfect, but deeply troubled family life: her father is having a long-term affair, her mother is insecure and obsessed with her (and Lara's) appearance, and her younger brother is angry and rebellious.
