2 States is written written by Chetan Bhagat. Who is a famous indian author known for writing books on his personal experiences in his Life. So I read this book when I was in 3rd year of my engineering and that time I was actually addicted to this book untill not finished.
It is a story about a punjabi guy who is an IITian and got admission in IIM where he meets a south indian girl. After few days they become friends then love each other. And the most addicted part of this book is when they both intimate with each in an inappropriate way but college students or readers are more attracted with this part.
When they finish their studies and got placement in two different companies, girl decided to work in his home town Chennai and boy got placed in a bank but he also decided to join in Chennai, so that he could convince girl's parents for marriage. Marriage problems go for long but end with a emotional happily married with the permission of both sides parents.
So I would say the best part is it will not bored you at all and make suspense till the end. Also written in very easy language so that anyone can understand that. Yes, you can't compare this with others literature special book but overall all I loved this book.
