Mishka Potapov lived all eleven years of his life on a farm, next to his father’s stud farm, but, oddly enough, he was afraid of horses and avoided them. But he knew how to misbehave and find adventures for his own benefit masterfully - one might say that this was his main talent. But one day the father brought a young horse - snow-white and mischievous, like Mishka himself. And something changed in Potapych: he began to grow up slowly and difficultly... For middle school age.
