Despite her massive size, Meghan Ball is the most invisible person at Valley Regional High. People say things in front of her as if she doesn't exist. And most of the time, she feels like she doesn't - until Meghan sees Aimee Zorn. Aimee is as skinny as Meghan is large, and as outwardly angry as Meghan is inwardly sad. Meghan instantly recognizes a kindred spirit in Aimee, another person using her body to say what she cannot. Alone, they are powerless, but together, Meghan and Aimee join forces to get sweet revenge against the one girl in school who hurt them both.
