I think the author knew how bad this book was and published it anyway on a lark! Maybe he wanted to test the blind faith his "readership" has in him and do they love him! This book was massively popular on release though its poor structure and ridiculous plot were well known. I blush every time Chetan Bhagat is considered the shining beacon of modern Indian Literature.
He explain how he met a mysterious girl on the train who narrated the story and how he had an epiphany. Simple explanation- he was probably high or incredibly tired from churning out trash-lit.
This book describes the sordid saga of Indian call centre employees. Trudging through ridiculous situations and horrible dialogues, one can find choice insults at the general American public. The characters in the book suddenly find true meaning in their lives when god decides to ditch his "booming voice out of the sky" routine and calls them up on a cellphone(coz they are call centre employees!).
Not recommended to anyone at all!
