The best of all the four of his novels till now, the basic reason being that the book describes an important (Indian) social issue in a very practical sense. The best of it is where he makes these statements at the very beginning:
"Love marriages around the world are simple:
Boy loves girl. Girl loves boy.
They get married.
In India, there are a few more steps:
Boy loves Girl. Girl loves Boy.
Girl's family has to love boy. Boy's family has to love girl.
Girl's Family has to love Boy's Family. Boy's family has to love girl's
family.
Girl and Boy still love each other. They get married."
Its a story Krish and Ananya's marriage, well basically a detailed description of what all they (I would rather say "he") go(es) through to make their marriage happen. The only reason that they have (he has) to go through all the trouble is that Krish is a Punjabi and Ananya is a Tamilian. Their family backgrounds are totally different, and so their marriage is not acceptable to either of their parents. Their efforts to get their parents to agree to their marriage starts on the day of their graduation from IIMA, the Act 1, which of course fails miserably. THey then decide to take it up step by step, one at a time. First, Krish goes to Chennai and tries very very very very.... hard to make her parents accept him. This takes 6 months, and at last his perseverance pays off. Step 2, Krish's parents have to accept ananya, so she comes to Delhi for just 1 week, the act 2. Again its his perseverance that pays off in a week with a very little of her effort. Step 3, their parent have to like each other. This calls for a neutral venue which happens to be Goa (act 3). It turns out abortive. Everything is called off, but he still doesn't give up even though she does. Suddenly out of nowhere, Krish's no good dad comes to the rescue and fixes the bungle. Finally, the marriage in Chennai.
It clearly shows that only guys always have "suffering" written on their foreheads...
