Ponniyin Selvan is my alltime favourite book by Kalki. I also like his other books such as Nandhipurathu Nayaki. But I read all these when i was in school. I dont remember everything, but some parts are so interesting that I could never forget them. I liked the paintings by Maniam, and Kalki's way of writing, the smooth flow. It was never boring to read the book again and again.
Nice to know that there are lots of fans for Kalki.
