I have read so many books about Indian subcontinent that I feel I know the culture better than my own. It seems to be very 'in' these days. Reminds me of latin-american literary boom of the 60's (not that I was actually around to remember it first hand).
Short stories are tricky things. There is no room for mistakes, clumsy paragraphs and lousy dialogue. You have about 20 pages to say what you have to say and make sure it is powerful and would leave an impression.
"Interpreter of Maladies" is a decent collection. The stories are written skillfully and are quite entertaining even if a little soppy at times. There is nothing to call home about though. They didn't knock me off my feet and I am a little baffled by the whole Pulitzer thing.
