I read this book quite a long time ago, back when sensual love stories with twist ending was not particularly mainstream in Indian book circuit. The book encases two humungous personalities, and a another one for dramatic appeal but either way, this book is a literal testimony of Chetan Bhagat the page turner.
The psychology of IIT aspirants has been delved into with quite a niche by Bhagat's hands. However, despite all the vividness lf the story setting and larger than life characters, the story- the plot is paper thin. You can see through all the webs of the subplots right at the end of it.
Overall, I can't say I didn't really like the book, because I did; it thrilled me no less, going on to the quality of the writing or the plot- it's average at best.
