Adiga has got this honour with his first book--that's amazing. I had no doubt about his talent ever since I had read some of his book reviews in the Time magazine. Perhaps at that time not many had noticed him but I had been impressed.
Here is the Guardian on his win:
After an "emotionally draining" and closely fought final judging session, Aravind Adiga, one of the two debut novelists on the Man Booker shortlist, was last night awarded the £50,000 prize for The White Tiger, a bracingly modern novel about the dark side of the new India.
Adiga, 33, is a surprise winner: at long odds he batted aside the claims of veteran writers on the shortlist such as Sebastian Barry and Amitav Ghosh.
He is only the fourth first-time novelist to win the Man Booker - after Keri Hulme in 1985, Arundhati Roy in 1997 and DBC Pierre in 2003 - and he is the second youngest after Ben Okri, who won in 1991 aged 32.
