In the separate world of teens and adults, meet two sassy ¿tween¿ girls, exact opposites, who decide to eat smart and change their body image. Join Olive and Amy O as they reluctantly draw on grownups to give them the expertise and knowledge they need to combat unhealthy eating, inactivity, and fast food to change their body shape. Shy, plump Olive finds her voice as she writes about their successes, secrets, and sabotages. The super-opinionated, lanky Amy O learns how to love her roots and be healthier too. This is not only a humorous book about healthy activity and food, but a book about family, feelings, friendship, and activism.
