Itās the last day of school before Christmas vacation and Alex, Chase, and the rest of Mrs. Walterās fifth-grade class couldnāt wish more for the final bell to ring. But the day takes a crazy turn when a mysterious meteorite crashes through the classroom windowāand a genie pops out! Bob, as heās called, is willing to grant only one wish for the class to share, and if they canāt agree on something before the bell rings in an hour, theyāll get nothing at all. What follows is a debate that is at turns thought-provoking and hilariousāand at all times irresistible.
