I had read both the books from the same author, It seems the first book was good 7 the second one he wrote just for the sake of it & to earn some good amount of money.
In the first book he showed as if it was his true story, Yes! It might be because after reading the second book I was bit disappointed . Now in the second book he says that he married the second girl & came out of the depression .
However when checked the WIKI the name of his wife was totally different. Such authors wants to mint money, just like that Chetan Bhagat.
