Jamie is a senior in high school and, like so many of her peers, doing too much. Unlike so many of her friends, she is enormously, irreversibly, sometimes angrily (and occasionally delightedly) overweight. Her most immediate need is a scholarship to college, so she writes an explosive and controversial column every week in the school paper about being fat. Soon, Jamie finds herself fighting for her rights as a very fat girl and not quietly.
When Jason Milwaukee's best friend Sunshine vanishes, Jason knows that something is terribly wrong, but solving her disappearance will require pushing through all the voices in his head and then getting the world to listen to him. His schizophrenia is stopping him from remembering the events leading up to her disappearance, and often he discounts his own memories, and his own impressions. But his deep knowledge that he would never hurt his friend, plus the faith of his parents and a few others in the town bring him to the point of solving the mystery.
