Серьёзная шутка джегуако

Sixth grader Matvey couldn't have imagined just a month ago that he would spend his spring break in a small mountain village, at an acting workshop — he had never participated in any performance in his life! But the workshop... turned out to be interesting, the guys were great, and if it weren't for the heavy thoughts that torment Matvey, everything would have been just perfect. Suddenly, strange and frightening things start happening in the hotel. To save his friends from impending danger, Matvey has to face the resurrected characters of Circassian fairy tales and legends. In this whirlwind of fantastic events, the boy must confront his fears and answer the difficult questions he was afraid to ask himself.'
