lolita would definitely be in my top 10 as well. i was never a huge fan of the great gatsby though...
i'm in the middle of the ishiguro book, "never let me go"...its a great book, with a lot of mysteries going on. It actually tempted me to flip to the end and read ahead, just to see what would happen.
btw sadia, what more was it that you had wanted to talk about regarding lahiri's book?
