The InvestiGators are back . . . to school? Mango and Brash have always been a class act, but find out whether these alligator detectives can go undercover as average middle-school students!

There's certainly something fishy going on, and many questions to be answered. Why has the super-spy organization S.U.I.T. been assigned protection detail for a small-town team mascot? Is it a coincidence that the school happens to be the same one that Agent Mango (just barely) graduated from? Is Mango's family in danger? Will Brash pass home economics? Is Friday still pizza day?

Find out in Class Action, the A+ return of the New York Times bestselling series by John Patrick Green! Read up, because there just might be a pop quiz later!
