An intriguingly offbeat mystery concerning the theft of cookies from a boy’s lunch, at turns humorous, suspenseful and poignant. Intelligent Owen is the fattest kid in his middle school, having packed on the pounds after a major upheaval in his life caused him to begin turning to food as a source of comfort. His younger sister, who has joined up with a group at school called Girls Who Are Boys (GWAB) and taken to insisting that others call her Jeremy, coped by growing tougher. Owen, on the other hand, has become an object of ridicule due to his weight. While the Oreo heist provides the main premise for Owen to engage with other kids at school, there are a number of secondary mysteries crafted alongside it, each of them raising unexpected questions that are neatly wrapped up by the novel’s end. While some readers may balk at some of its more convenient coincidences, fans of Jerry Spinelli and others of his ilk may especially enjoy it and will be held rapt. (Mystery. 9-12)
