Fifth period is hands down the best time of day in Connor U. Eubanks Middle School, because that's when Mr. Lewis teaches Jazz Lab. So his students are devastated when their beloved teacher quits abruptly. Once they make a connection between budget cuts and Mr. Lewis's disappearance, they hatch a plan: stop the cuts, save their class.

Soon, they become an unlikely band of crusaders, and their quest quickly snowballs into something much bigger--a movement involving the whole middle school. But the adults in charge seem determined to ignore their every protest. How can the kids make themselves heard?
