Claudia, Queen of the Seventh Grade

At first, Claudia hated going back to seventh grade. But things are definitely improving. She's on top of her schoolwork, she's made some great friends, and her new classmates really look up to her--so much that they nominate her for Queen of the Seventh Grade. And when the votes come in, the results are clear: Claudia's not just adjusting to seventh grade, she's ruling it!
Being queen is harder than it looks, though. There's a ton of work involved. And Mark Jaffe, the newly elected king, is no help at all. Claudia's determined to stop him from turning her glorious reign into a royal mess. but how?
