Coop Cooperson thought he was settling into life as the only human at Dungeoneer Academy, but no one will even remember his Mushroom Maze victory if he keeps failing Riddles and Runes class. Adding insult to injury is the new kid, Kody, who everyone—including Coop’s best friends on the Green Team—thinks is great...but Coop is convinced there’s more to Kody than meets the eye. But it’s not just the arrival of Kody; other things seem off at the Academy. After a serious incident at the school dance, Coop, Oggie, Daz, and Mindy, plus a few other students new and old, realize they must step up to try and stop whoever’s wreaking havoc. But the villains are even more dangerous than anyone realizes...and they have a serious vendetta against Dungeoneer Academy. Coop and his friends put their best junior dungeoneer skills to the test, but their foes are always one step ahead. Can they figure out how to stop them and save Dungeoneer Academy before it’s too late?
