I think its a different story from your past books. Its makes me really interesting to know who the killer is and i read it within 2 days.. that is in 2 stretch itself. I really loved it and i wish you could write such sort of books more. And i have a question towards you mr chetan bhagat why you always writing the stories of IITians or IIMians? Is this because of you from there??? You can my story as well😁... Anyway it is really amazing and i suggest my all friends to read...
