Parents need to know that this book is trying to be edgy for its young target crowd, but it's mostly about attitude. Daniel does lie to his mother and teacher. When Daniel shrinks, he and his tiny brother engage in some potentially dangerous acts, like catapulting themselves with rubber bands -- but kids couldn't emulate any of it.
Positive messages:Daniel has a TV in his room. He is a slob and has questionable manners ("if you cover your mouth when you burp, you're just going to wind up breathing in your own gas"). Teen girls are presented as shallow, only talking about "hair and lips and shoes and mascara and boys and deejays and -- oh, did I mention hair?" With his grandmother's help, Daniel lies about being sick so he can stay home. Daniel lies to his teacher so he can take home a cockroach to scare his sisters during their party.
Violence:A brief mention that Daniel's father is dead.
