This is a Pulitzer prize winning collection of short stories. It sometimes, misleadingly, is placed on best Indian books lists. Instead, the author is a first generation immigrant to the West, and while some works deal exclusively with India, the majority are about the immigrant experience and/or the clash of Eastern and Western cultures.
I'm not sure if the stories are organized chronologically in the order in which they were written, but they absolutely improve as they go along. I despised the ending of the first two stories in the collection, but the later stories are more assured. The collection is quite good, and also varied. It is not astonishingly good. I think some of the acclaim for it is that it has a window onto the exotic, while being written by someone with at least one foot in the west.
Its worth reading and is good, but not great. The prose is good, the character studies are good, but there is nothing here that will burn its way into my brain forever.
