From a fresh and funny debut author comes a warm-hearted, laugh-out-loud adventure about a brother and sister who must solve a magical riddle in order to get their fondest wish. Harlan and Ainsley Banana are on a mission. An exciting, dangerous, once-in-a-lifetime quest for the perfect stepmom to cheer up their sad dad. Harlan and Ainsley bump into a wish-granting creature called a frongle (not ever to be confused with a fairy!), & they learn that their wish can come true if they solve a magical riddle. With a rainbow-colored creature named Zucchini Spacestation as their unreliable guide, the brother and sister head off. But help from unexpected allies --- such as a pair of purple martian twins -- might just make Harlan and Ainsley's wish come true after all!
