Rudravan by Rahul Rajan is about a purpose to live, a reason to exist. This is what Ravan was seeking throughout his life. In fact, Ravan is the lead character of this excellent book. Everything else revolves around him in one way or the other. As a matter of fact, the reason of Ram's existence seems to be Ravan itself. If Ravan was not into existence, there would have been no need for Vishnu to take birth as Ram on earth. The story is predominantly a war between light and dark.
