At 13, CJ is already a hot DJ. Cathleene Jones, aka CJ the DJ, is so enthusiastic! Every time she gets the opportunity, she works in her neighborhood music store, and thanks to Arnis, she goes from concert to concert as a DJ. She plays at parties, store openings, CJ's here when there's good music! CJ has very different friends, including her neighbor and best friend Si, a jazz musician. There's also Lesley, the brains, more often in a book than on a dance floor.
