After reading this book, I am going to watch the movie Zubeidaa too, as I wasn't aware of the connection between the central character and the author of the book. The book has a charmingly real feel and the stories illustrate highly detailed images in the mind of the reader.
The book is not easily available so I'd say order it quickly. It is one of those books you'd read over and over again because the sensitivity with which Khalid Mohamed describes relationships is commendable, unveiling new layers of meaning with every reading.
I have already ordered another book of short stories by the same author.
