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