Chetan Bhagat's books are tailor-made for the Indian reader. All his stories revolve around friendship, love, sex and emotions, and his books read just like Bollywood movie scripts. Which explains why 3 Idiots, Hello, Kai Po Che and 2 States are all movies adapted from his books. But come to think of it, there isn't much in terms of a plotline in any of his books. All of them can be explained in one sentence each.
