It's an eventful month for Jamie Kelly. Stinker and Stickybuns' litter of puppies has arrived, which makes Jamie and her nemesis Angeline "in-laws by dog." Ugh. Jamie's class at Mackerel Middle School is doing a unit on journal-writing, and someone's diary falls into the wrong hands. But worst of all, Angeline and Isabella are becoming...friends. Dear Dumb Diary, It's not my fault I know everything. Okay, I don't know where Timbuktu is, but I refuse to know that. Even if somebody told me, I would flush my brain like a thought-potty and wave goodbye to Timbuktu as it swirled down my brain hole. I know everything that I want to know.
