In the latest installment of this funny foodie series, eight-year-old Dessert and her friends are exposed to a highly contagious disease—the Annoying Sibling Disease. It's up to her to come up with a plan to stop this deadly disease, and when her class embarks on a study of the American Revolution, Mrs. Howdy Doody inspires Dessert to form a club and fight back. But as president of the Annoying Siblings Club, Dessert bites off a little more than she can chew, and in the end, she learns that to have a good friend or sibling, she has to be one.
