In the life of every schoolboy there is a place for magical feats - and the life of Denis Kotik is the best confirmation of this. Becoming a student of the Russian magic lyceum, he plunges headlong into the whirlpool of incredible adventures and, together with new friends from the Pathfinder Posad, conducts his own detective investigation. This witty book combines the advantages of a fairy tale, a child detective and a dizzying computer game - after all, it was invented by the famous Russian science fiction writer Alexander Zorich, a professional screenwriter of computer games.
