Book excerpt: Olivia has just about had it with the popular kids at school. She and her friends have done nothing to deserve evil pranks and awful name-calling, but that doesn't stop queen bee Brynne from humiliating them on a daily basis. If only Olivia's classmates were more like the adorable dogs she helps her grandmother train-poorly behaved, but improvable. Wait . . . what if her tormentors' behavior actually could be modified using the same type of training that works on dogs? Olivia and her friends are desperate enough to give it a try. But is it really possible that the underdogs of Hubert C. Frost Middle School could make it to head of the pack?
