Recently read Pakistan or partition of Indian by Dr B R Ambedkar.
It gives a good description about the forces which created our nation. Though written in a intellectually abstract way Ambedkar's view on the question of Pakistan is also very clear in the book.
The book is a bit slow in parts and could be heavy reading for many people.
In my opinion the book still retains relevance in present day India.
Overall a good read for political junkies.
