Yes, I know ON@CC release ages ago, but ever since its movie-version, Hello, released, interest over the story seems to have increased. That prompted me to read the original story, because movies are infamous for changing the plot altogether. I definitely recommend this book to anyone who: a) thinks he or she represents the youth; b) wants to understand the youth; c) hates call centres; and d) is an American.
The book is excellent and provides some good reading and some moral lessons as well. Do take some time and find a copy for yourself. You can watch the movie, but from what my friends tell me, it isn't worth it. I recommend the book.
Chetan Bhagat's other books are Five Point Someone and The Three Mistakes of My Life.
