Actually, Arkasha is a zombie knight and brother of the dragon. But no one suspects this: neither mother, nor older brother, nor classmates: no one, no one. For those around him, Arkasha simply studies in the fifth grade, sometimes he is lazy and does not like to read. Arkasha does not yet suspect that this autumn will change his life a little. He will almost lose his best friend (not really). He will almost lose his hearing (also not quite). But Arkasha will find a cat, and Arkasha will find a name for him. And Arkasha also learns stories about her father, whom she hardly remembers, and her great-grandfather, whom she has never heard of.
