Coming to visit your grandmother in the village for the holidays and finding yourself in a fairy-tale kingdom where Zmey Gorynych, Koschey the Immortal, Dashing One-Eyed, Cat Bayun and other fairy-tale, unattractive people live—not every boy will like this. But Mitya Sidorov really liked it all. Because he not only saw what he read about in books, but also managed to help good fairy-tale heroes: Vasilisa the Wise, Uncle Brownie, Baba Yaga and Tsar Makar. How did the city boy Mitya end up in the fairy tale kingdom? Yes, it’s very simple - he turned out to be a relative of Baba Yaga.
