Beloved children's author Elise Gravel asks the eternal question: Who made all this mess? When their dad asks who left socks everywhere, Nico and his sister both answer, "Not me!" Their dad is sure they're not telling the truth, until they introduce him to Not Me, which accuses Not True, which reveals the real culprit: Not Fair. The monsters, which personify typical child responses, allow the author to brilliantly and humorously address the issue of blaming others and making up excuses. Parents and educators will love this story, which they will recognize as much of themselves as the children.
