In this hilarious sixth middle grade book in the Middle School and Other Disasters series that started with New York Times bestseller Worst Broommate Ever!, witch-in-training Heidi Heckelbeck has a new rival. Featuring black-and-white illustrations, doodles throughout, and sparkly foil on the cover!

When a new student comes to Broomsfield Academy, Mrs. Kettledrum informs the students she is an extra-talented witch-in-training. At first Heidi is intrigued and wants to be friends, but when Jodi tells Heidi she intends to be the best witch ever, a competition brews between them and bubbles over while on a field trip to a museum—which becomes more dangerous than either could have imagined!
