Continuation of the story about Kira, Glasha, Polina. The boys turned thirteen years old. Polina is leaving on a school trip to France. And Kira’s life develops in such a way that he has to leave for Lysofange forever. Glasha and Kira walk around the city for the last time, but after passing through the waves on the wall, the guys find themselves not in Lysofange, but in Paris, where Polina is. Polina fails to draw waves that would return the guys to an imaginary world. Tired of wandering from hand to mouth, Glasha and Kira settle in a French family instead of Polina: Kira hides her presence, and Glasha pretends to be Polina. Polina, meanwhile, is trying to cope with her crush on a high school student and return Lisofange.
