If the situations you vividly imagine are never repeated in real life, then you are also a dimeurge, like the young man Klim, one of the main characters of this philosophical and fantastic story. And if you cannot logically explain your conclusions, but are often right, then you are a stalker, just like Lisa, another character in this work. The two of them, as it happens in literature, will have to save the world, twice. And they will be helped by extravagant guests from other worlds and Antonina Vasilievna, the artificial intelligence of the school where young people are graduating.
