"Greta is a handful. She rips the heads off her dolls, lashes out at the other kids at her school, and tries her weary parents' patience. But with the help of a dapper tortoise named NoBody, Greta softens her grumpy ways. Having learned her lesson, Greta must now team up with her new friend Gabby and their shelled companion to solve a strange mystery: Why have the kindhearted denizens of Friendlytown suddenly become so mean? And what can they do to make Friendlytown friendly again?"--From publisher.
