There are several snort and laugh out loud moments in this book, and older readers will remain clueless as to why there is such a to-do about the principal's size DDD brassiere. But intermediate readers, especially girls, will find this title quite entertaining even though the outcome can be seen from miles away. Sixth grader Becca Birnbaum is lost in the crowd at James A. Garfield Middle School. Anyone who's ever attended middle school can attest to the fact that sixth graders are the lowest of the low there since eighth graders rule that world. When Becca accidentally injures eighth grader Sloan St. Clair, known as Selfie for obvious reasons, their paths come together under the most unlikely of all circumstances. Because Becca feels responsible for Selfie's injury, she tries to make up for things and agrees to retrieve a shopping bag from the principal's office. But it's the wrong bag, not Selfie's but Dr. Jasmine Valentine's, the principal. Obviously, the girls need to get that bra back to its rightful owner, but before they can do so, it's stolen for a devious act that would embarrass the principal and get the girls in trouble. Although it's all too predictable and somewhat silly--why not just tell the principal about the confusion over the same bags?--I liked how Selfie turned out to have more depth than might be expected and how Becca actually comes to like her without changing too much about herself. It's a breezy read that left me feeling entertained and smiling. I would read another book about these characters, and I'd recommend this one to those who enjoy Diary of a Wimpy Kid, The Popularity Papers, and The Dork Diaries. Still, there's quite a lot of running around as those the girls are chickens with their heads cut off and more than a little helplessness on the part of Selfie. It's necessary to be a certain age to appreciate humor concerning farts, toilets, and underwear, though.
