At the beginning Ignat seems the Secret ring of City roofs lifts them to the sky and does their not such as all. The boy believes he has found the true friend at last. But George is able neither to be friend, nor to love. He’s typical modern "kid-alt" (the adult child), George is infantile and he can’t appreciate relationships… This story has something in common with well known story about the Kid and Carlson - it shows the teenager growing in the fine and inconsistent Moscow city.
