Racheal and the mean girls

This book is about a little girl who has been bullied for not being as skinny as the rest of the girls in her class. She ends up starving herself to try to be like the other girls. The teacher finds out and has a talk with the class about this situation. She talks about how it doesn't matter on what you look like on the outside, but what is on the inside. You don't have to be skinny to be accepted and it is wrong to judge people for how big or small they are.
