Synopsis
Fifth-grader Cody Carson keeps a journal of his hopes for a fresh start in a town where nobody knows about his humiliating mistakes of the past, but before school even begins so does his embarrassment. As he goes through many things at his new life, he encounters many challenges, crushes, adventures and embarrassing moments. Will he be able to become a "New Me", without shattering into pieces?

Reception
Critical reception for Attack of the Mutant Underwear has been positive. Publishers Weekly gave a mixed review for the book, writing "The author hits a few shaky notes (e.g., Cody's disdain for cleaning his cat's litter box becomes tedious; his infatuation for Amy stretches credibility, as when he refers to himself as "Loverboy" in his journal). But many passages compensate for them—including the way Cody couches his bungling of the talent show as a step-by-step formula for creating a "really good disaster.""
