The Last Kids on Earth gets a fantasy twist in this third book in the middle grade Dungeoneer Adventures series following Coop and his friends as they sneak along on their professors’ quest to save Eem.

Hero dungeoneer Shane Sandar has been missing for weeks, and the professors at Dungeoneer Academy fear the worst: that he’s met a terrible fate at the hands of the villainous exiles. When Coop Cooperson and his best buds on the Green Team discover their professors are taking a dangerous voyage to try and rescue Shane—and closing Dungeoneer Academy in the process—they know they can’t let their professors go alone, so they secretly tag along.

It’s not long before the professors are captured, which leaves it up to Coop, Oggie, Mindy, Daz, and unlikely new ally Zeke to try to rescue Shane Sandar, help their beloved professors, and save the Land of Eem from the terrible fate the exiles are planning. But can a ragtag group of junior dungeoneers stop a group whose leader is pursuing the power of the Wishing Stone, the most powerful magic in all the land?
