Koschei's Daughter and Granny's Granddaughter

Varya is an ordinary girl. She is in the third grade and cannot imagine life without the Internet and mobile communication. But in her grandmother's village, where Varya has to spend the summer, there is none of that. To pass the time, Varya plays detective. But reality turns out to be much more exciting than the game. Incredible adventures await Varya in Zarechye—a world of fairy tales and legends, inhabited by heroes, wizards, centaurs, and dragons. And where there are adventures, there are dangers. And to win, Varya needs courage, bravery, and the ability to think.
