Baba Yaga, the brownie, the mistress of the Copper Mountain - all these characters met in distant childhood. And, of course, they did not arouse any interest in the present. At least for Denis. At least until a certain moment. Namely, until the treacherous parental decision to send him from his beloved capital to a distant town in the south of the country. To go to a special school with your own aunt. What could be worse for a teenager who is accustomed to his company, his city and his hobbies? Perhaps the news that everything is not what it seems? And the fact that he is not who he thought he was all his life? Or, for example, a sudden desire from outside forces to get rid of him as soon as possible? The answers to these questions will have to be found by the hero and everyone who happens to be nearby.
