School vacation for a year. Eternal happiness. Would you make a wish at the expense of someone else? That's the catch thirteen-year-old Gabe Silver faces in this delightfully funny middle grade novel. When a mysterious millionaire sells Gabe a bottle containing a wish-granting imp there's just one caveat: any time Gabe makes a wish, someone else, somewhere, is going to lose something--maybe something big. That means each of Gabe's wishes should be an ethical dilemma--but as he scores a Ferrari, a hot tub, and all the pizza and sub sandwiches a kid could want, he's certain a guilty conscience is worth it...isn't it? This thought-provoking book, inspired by a Robert Louis Stevenson novella, is pithy, dark, and very, very funny. References to Robert Louis Stevenson's work is peppered throughout the narrative for readers to discover, while Gris Grimly's bold artwork brings the story to life.
