"Down the Magic River" is a witty, funny story by E. Uspensky based on Russian fairy tales. An ordinary schoolboy Mitya comes to visit his grandmother in the village for the summer and finds himself in a Far-off kingdom. There are all the characters familiar from childhood: Snake Gorynych eats people, Baba Yaga can also eat, but mostly welcomes princes, feeds, waters, puts them to bed. Koschei the Immortal is all made of iron, hung in the basement on chains for two hundred years. And then such an opportunity presented itself: Tsar Makar was going to retire. So the "devoted" royal servants offered to take the throne to Koshchei. And the change of power is rarely peaceful.
