Strange things are happening at Ho-Ho-Kus Junior High. The cafeteria's covered in a sea of burger wrappers. Bullies aren't bullying anymore. And there's an eerie growling coming from the walls.
If anyone can get to the bottom of these mysteries, it's Denton, Wendell, Eddie, Elijah, and Bijay. They may be misfits, but they're also the smartest kids in the eighth grade. There's just one problem. Vice Principal Snodgrass has framed them for a crime they didn't commit and imprisoned them in a secret room in the bowels of the school. His terms: Ace the dreaded Idaho Tests and all will be forgiven. Their plan: figure out who—or what—is to blame for the changes at school.
It will take the nerdiest of skills. It will be a test that can be passed only by a select few, a.k.a. Dweeb.
