May Contain Buts is an installment in The World of Norm series. The title is a humorous pun on the phrase "May Contain Nuts" and refers to the constant stream of excuses, exceptions, and unfortunate caveats that define Norm's chaotic existence. The plot details a series of events that seem promising but are inevitably derailed by a disastrous "but." The book uses Norm’s diary-style narration to detail his ongoing struggle against the unfairness of the world, maintaining the series’ popular blend of British humor and teenage angst.
