Peggy Sue led a wonderful life: she destroyed evil ghosts, pacified enraged enchanted animals, defeated underground monsters... but most importantly, she has not been to school for some time! Her parents sent her to her sorceress grandmother, in a town where there were so many eccentrics that no one would pay attention to Peggy’s amazing abilities. Everything was going nowhere better, when suddenly a certain gentleman brought the girl a letter instructing her to immediately go to study at a college for superheroes. But getting a diploma turns out to be not so easy: the final exam will be held in the Martian jungle! There, among the red vines and baobabs, where high magic reigns and a new danger lurks behind every tree, Peggy Sue and the blue dog will begin the most amazing monster hunt in the world!
