Gripping, unexpected turn of events, unimaginable ending, little abrupt ending but definitely a good thriller.
You won't be expecting the end. When I was reading the climax it blew my mind in such a way that I had to re-read certain lines to digest what I was reading , maybe because I wasn't expecting that. I am writing this review because I have finished the book 10 mins ago and its still fresh in my memory. How it all happened. Its taking time to absorb. I don't think a movie on this book will be able to do justice to it. Its that good. Do give it a read.
