An Amazon Best Book of the Year

DING DING DING!! Is that the school bell, or is it three million readers ringing in the return of V.E.S.T.-wearing case-busting secret agents Mango and Brash for another hilarious adventure? (It's the latter, we'll solve that mystery for free.)

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