When a shopping bag goes missing from the principal's office, a sixth-grade "nobody" is recruited by Selfie, the most popular girl in the eighth grade, to help solve the mystery in this contemporary middle grade novel. " Will be appreciated by readers who enjoy mean girl stories, the Diary of a Wimpy Kid and Dork Diaries series, and other school survival tales .” — School Library Journal When you're a sixth-grade nobody, the last person you want to accidentally zonk with a volleyball is Sloan "Selfie" St. Clair—the eighth-grade glamour queen of the school. But that's what happens to Becca Birnbaum, and it only gets worse when she tries to do Selfie a favor. She grabs the wrong shopping bag from the principal's office—one containing a very personal item. And even that might not be so bad, if only Selfie didn't immediately lose it. If they don't get it back ASAP, they're toast. They try not to panic—until they hear that the Biggest Prank Ever is about to happen. Can the school's oddest couple stop the disaster of a lifetime? Full of laughs and hijinks, Holly Kowitt's The Principal's Underwear is Missing is a delightful, illustrated read about middle school cliques, unexpected friendships, and one hilarious misadventure after the next. Praise for The Principal's Underwear Is Missing : “In this amusing read with its Wimpy Kid—like line drawings, kids will learn that it's OK to associate with someone who's different—you might even have fun. . . . Kowitt's well-written title gets school social dynamics right and will be appreciated by readers who enjoy mean girl stories, the Diary of a Wimpy Kid and Dork Diaries series, and other school survival tales.” — School Library Journal "Along with an arresting title and laughs aplenty, this helter-skelter caper features two middle-schoolers who aren’t quite as typecast as they seem. . . . Kowitt’s cartoon insertions supply the romp with punchlines and wry visual commentary." — Booklist
