India After Gandhi is truly a powerful book, and you're right in saying that it is our duty as an Indian to educate ourselves about post-1947 happenings. My only issue with the book, though only slightly, was the fast that Guha was a bit too soft on Nehru. There were many flaws/bad decisions (and good decisions too indeed) taken by Nehru which, I think, the book downplayed.

Nevertheless, Guha is truly an amazing historian and all of his books deserve to be read!
