I copied this from Amazon.com :
"Virginia Shreves lives in Manhattan and attends a prestigious private school. She lives by her Fat Girl Code of Conduct. She has a budding romance with Froggy the Fourth, but she doesn't want his wandering hands to feel her fat. Her baggy clothing helps her to "hide." Her mother, Dr. Phyllis Shreves, is an adolescent psychologist obsessed with her imperfect daughter's weight, and her father is rarely around. Her older sister joined the Peace Corps to escape mom, and brother Byron is big man on the Columbia campus-until he's suspended for date rape. Finally, Virginia stands up to her mother and takes charge of her life."
