Nineteen minutes is barely a bus ride, and that is the whole proposition of Family: A Short Horror Story. Syon Das is working in the miniature, where a piece has to unsettle you before you have properly settled in.
Our catalogue files the story on the teen and young adult shelf, though the subtitle is the more honest guide to what you are getting. This is horror, compressed. The short form suits the genre unusually well, since fear needs no world-building at all, only a situation, a voice and a turn you did not see coming.
