One of my quickest reads was last week when I was in Bangalore, where I had plenty of time to read, compounded by flight delays in both directions. Nayantara Sahgal's Rich Like Us is set in the time of emergency (1975-77) and shows how the power change affected different people. While some bore the brunt of the harshness of the regime, others profited from it and reveled in it.
Sonali is an idealist and a bureaucrat (a total contradiction in present times) who is forced out of her job when she objects to the set up of an 'irrelevant factory' of Happyola, which is being backed by Dev, the stepson of her friend Rose. Dev, is one of those who profited from the emergency, uses any means to reach his goals, whether it may be forging signatures of getting someone murdered.
All in all an interesting read about India during those unstable years.
