Henry is up to his usual mischief: annoying his younger brother, ruining Moody Margaret's sleepover, and irritating his teacher, Mrs. Battleaxe-not to mention trying to manipulate his family into seeing his favorite band-the Killer Boy Rats. "Kids will love reading the laugh-out-loud funny stories about someone whose behavior is even worse than their own." -School Library Journal "Not since 'Nate the Great' has an early reader series created such a buzz." -Los Angeles Times "Will engage even the most reluctant readers." -Publishers Weekly
