If the launch of the Netflix show, controversies around subtitling and a PIL to defend Rajiv Gandhi’s honor has not made you curious about Sacred Games by Vikram Chandra, I don’t know what will! It is a voluminous book (I own the paperback). So, while you may not be able to finish it before watching the series, you might want to grab a discounted version on Kindle (Rs. 139)!
Also available for only Rs. 17.70 is Krishna’s Secret by Devdutt Pattanaik if you are a fan of his mythological research.
Another book I came across is The Fisher Queen’s Dynasty by Kavita Kane. It is priced at Rs. 69. I don’t know anything else about the book, but the premise of a book on Mahabharata with Satyavati as the determined protagonist sounds interesting. Check out if you would like to give it a try.
