This novel half girlfriend is very nice and attractive novel. In this novel chetan Bhagat share his real life experiences so nothing is good than real life experiences. I love this novel it guides us to the good direction. And chetan Bhagat is IIT student. So nothing is better than it. One movie is also comingon this book that movie name is also half girlfriend, so you can imagine that if this book is not good so why they create movie on this book. I am telling you must have to read this book this is wonderful book and you can check its rating also.
