I don't know why i pick Chethan Bhagat to read. I've read his latest(?); '2 states' which can be termed typically Bhagat. Like there is a Karan Johar film and though you know it's silly and very much avoidable, you still want to watch it. Considering the two options that i've given here, i think i'll go with Bhagat.
It's not a you-can't-do-without-it read. I wanted to read something which was light and would not make me go back to it a couple of times and hence exercise my brain. And maybe i wanted to read all what Bhagat has written (can't figure out why!). Read if you've really nothing to do and can waste a couple of hours.
