My Nanny is a Witch

When ten-year-old Petya gets a new nanny, who is strange and grumpy but incredibly charming, he quickly realizes that she is different from everyone else. She is an "undercover nanny," but in reality, she is Yaga, a legendary sorceress who has lost her stupa and hidden among the people. Now, only Petya can help her regain her magical powers, and Yaga can teach the boy how to fly. Not just in a stupa, but in life.
