Any One Read "Q & A" by Vikas Swaroop...
Interesting story of how a waiter at a Mumbai bar wins the top prize at Who will become a Billionaire( similar to kaun banega crorepati with even more money)
the author captures the life of the protagonist in an interesting way and how he goes on to win the billion rupees!!
bit bollywoodish but i am sure you will enjoy it!
it can be read at one go.. try it over some weekend!
