One principality was ruled by a selfish and cruel Prince. First of all, he always thought about himself, and not about his subjects. He was not touched by the complaints of the townspeople; he sent their written requests into the fireplace and laughed at them. There was a lot of injustice in his kingdom, rivers of tears flowed, the rich oppressed the poor and took the last for the treasury. In the same country there lived a young man with his mother. He worked all day, feeding not only himself and his mother, but also all the hungry people who did not have money to buy food. He gave shelter in his small house and often gave his last on the road. And one day the unthinkable happened: they swapped places. The book contains Christian and Slavic motifs from the time of Rus' of the 10th-13th centuries.
