Though I'm not a fan of short stories, I enjoyed Interpreter of Maladies and The Namesake as well. There was a blurb on the back of this book saying that Lahiri has a gift of using simple language to create heartbreaking characters and quite honestly, that's the reason why I've really liked all of her works. Unaccustomed Earth is no different - a series of short stories/novellas about Indians living in America and their problems/experiences combining their Americanized culture with that of their ancestry.
The second part of the book has a series of related stories linking two characters (Hema and Kaushik) and their lives together and apart. The only problem I had with this book was that I could predict the manipulative ending about 10 pages away. Usually I'm not good at that.
This book is fabulous and awesome and amazing and depressing (but in a good way). Everyone should read everything by Lahiri. Case Closed.
