With her irresistible urge to tell a joke in every situation - even when she really, really shouldn’t - 12 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.

But no matter how much fun Jacky has, she can’t seem to escape her worries. So one starlit night, she makes a promise to keep her family together … even if she has to give up the one thing that makes her happy. But can she stop being Jacky Ha-Ha, if that’s who she really is?
