A new hilarious title from one of the biggest-selling authors of all time. Jacky Ha-Ha likes to tell jokes in every situation, even when she shouldn't! But can this class clown keep her promise and stop telling jokes in order to keep her family together? Ages: 9-11yr With her irresistible urge to tell a joke in every situation – even when she really, really shouldn't – twelve-year-old Jacky Ha-Ha loves to make people laugh. And cracking wise helps distract her from thinking about not-so-funny things in her life, like her mom serving in a dangerous, faraway war, and a dad who's hardly ever home.
