There are different layers of non-fiction and arousing non-fiction, I say, is the most active art of writing non-fiction. So, what is that you may ask. For me, a book in the non-fiction genre that lets your hair rise and allows your mind to become super active is arousing non-fiction. I have read many books in this category and recently I have read a number of books that I can call arousing non-fiction literature. I will be sharing my experience with you in the coming days. Today, let me talk about one such book – I-Spy: A Peep into the Wold of Spies by Amit Bagaria, an accomplished writer of books on international politics and Indian history and strategic and war affairs.
