All of the kids in EllRay's third-grade class have something to brag about-Kevin is really tall, Corey's on the swim team, and Jared's dad has an ATV. EllRay doesn't have anything to boast about, except that his dad, a geologist, collects rocks. And that isn't very exciting-or is it? EllRay decides to "borrow" six of the crystals in his dad's office to show his classmates in his attempt to become a "rock star."
