Jamie Kelly is back and dumber than ever in this super-deluxe four-color Dear Dumb Diary special edition! Life at Mackerel Middle School is as dumb as ever -- but Jamie Kelly may have finally found the key to fame, fortune, and fabulousness. Together with Isabella and Angeline, she's come up with a moneymaking idea, and it has to do with food. Everyone likes food! They're going to be rich! The only problem? They have to come up with something that people actually want to eat. Jamie has some sophisticated thoughts on food, like, "She was manipulating us like dough. Like the sweet, delicious dough that we are. And she was baking us into the type of delicious cookies you can only get from dough like us. And she was putting sprinkles of us on top of us, and -- forget it. I'm hungry. I want some cookies." This is sure to go well.
