David doesn't like vacations. Because during the holidays he has to return to his uncle and aunt - to the house, where he is constantly reprimanded, pulled back, instructed and at the same time demanded gratitude for his care. Honestly, David is grateful to them, but this time his patience ran out. Not only are the relatives endlessly nagging, but they are also planning to force David to study mathematics - just so they can go to the resort without him! Offended, David decides to place a curse on his relatives - and he succeeds! The ground shakes underfoot, flames are raging all around, giant snakes are climbing out of somewhere... And in the midst of all this fiery chaos, a red-haired boy named Luke appears, who claims that David freed him from captivity... David will have to spend eight days in the company of a new friend, and these days will forever change the life of David himself, and his relatives too. For the first time in Russian!
