Mr Sinha is an accomplished person, who's been places in his various capacities. This reflects in his chronicling effort. There are numerous anecdotes and insights relating to the bureaucracy and Indian politics.
Personally, I enjoyed this book a lot because he contested his elections from my hometown, Hazaribagh. I might have given it 3/5 stars otherwise.
I had a couple of gripes though:
1. At times, the book sounds like a hard sell. I suppose that becomes second nature being a politician.
2. He ignores the UTI scam altogether. My family tells me he faced criticism for the rapid capital reduction. This is confirmed by a quick Google search.
All in all, it's an interesting read. If you want to learn more about the politics of the unstable 1990s, I suspect there are better books than this one.
But if you have a personal/professional interest in Mr Sinha's journey, it's a good read.
