It's tough for eleven-year-old Ned to stop eating. At four-feet-eight inches tall he weighs one hundred and nine pounds, and he keeps growing--wider. When his pareents send him to a summer diet camp, he and his bunkmates can't quite give up their old habits. The joys of candy and doughnuts are so appealing that "cheating" adventures seems to be the only answer. The problem, of course, is how to lose weight and keep eating sweets. When Ned finally realizes that there is only one way to lose weight for good, his whole family is glad to help, except Grandma. How can he resist temptation without hurting his grandma and himself?
