Poonachi: Or the Story of a Black Goat by Perumal Murugan is available in Kindle version for ~Rs. 97 and hardcover version for Rs. 102. The hardcover version is slightly tricky though, because as of now, it is the regular price that shows us as Rs. 102. If you click on the “Deal of the Day” link, it actually takes you to the higher priced version! So stick to the regular price one, if you are buying hardcover (I just did!).
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.
