Witch, cat and the trick

The parents of seven-year-old Genka disappear without a trace in the distant African jungle. Only a miracle can bring them back. Where are miracles found? Of course, in the attic of the evil witch who lives next door. And it... doesn’t matter that the house is infested with poisonous snakes and bloodthirsty giants; for the sake of his parents, Genka is ready for any feat.
But it turns out that he is not the only one who dreams of a miracle: in the attic, Genka meets Mr. Black, a wizard who a hundred years ago was turned into a cat by a witch who lived here. Mr. Black is looking for a magic crystal that can grant two wishes once every hundred years.
The friends have adventures and unexpected discoveries ahead, which show that in life not everything is always as it seems at first glance.
