In the Thirteenth Edition they are already accustomed to visits from the supreme authorities. Castor arrives, scares everyone, and the adventure begins. But this time he will not scare anyone - he will simply praise them. And to hear his praise and not lose consciousness from the overwhelming feeling of pride is not an easy task. But this is a complete trifle compared to what the Mungs have to do this time. A mysterious second-hand bookseller, rising stars of an amateur song, a director of a cult film, an alien ghost, as well as shemobors, bearers of desires and random passers-by will help and hinder them as best they can. The work week will begin at the meeting, and even Castor does not yet know where it will end.
