"SuperJoe -- superhero in the making -- is far too busy to say sorry. He tears around the house sending invading space aliens back into orbit, rescuing passengers from sinking ships, and bravely facing prehistoric perils, while leaving a trail of broken toys, spilled bath water and displaced goldfish in his wake. But one sound keeps interfering with his supersonic hearing ... and that's the sound of his little sister crying. Can SuperJoe swallow his pride and say the one little word that will make everything better?"-- Front jacket flap.
