Bestselling author Jamie Kelly is back with an all-new, all-funny diary! But she has no idea that anybody is reading it. So please, please, please don't tell her.

School's out for the summer, and that means no more Meat Loaf Thursdays, Sunday homework-cramming, or teachers (way way unsuccessfully) trying to act cool. It also means that certain Mackerel Middle Schoolers have a lot of time on their hands . . . and seriously empty pockets. Isabella is going to change all that. And Jamie and Angeline are going to help --- whether they like it or not. It's the best kind of teamwork: When a whole bunch of people work together to do something wrong, instead of doing it wrong one at a time.
