Gordon Korman meets Scooby-Doo when anxiety-prone middle schoolers try a mindfulness app that has them face their fears all-too-literally in this spooky, “humorous, and heartfelt” (Publishers Weekly) middle grade adventure.

Can Lena’s group of worriers figure out how to conquer their fears before the whole school is swarmed?
