I loved reading this book.
Character of Alia and Keshav seemed to be quite real. And their efforts and never give up attitude to identify Sia was commendable. Keshav friend reminded us health aspect and it's significance time to time.
Ending could have been much better. About Roy and punishment to Priest..
But never mind, I'm the fan or urs Chetan Bhagat and have read all of the books.
My opinion Revolution 2020 was the best ever read.
