For people interested in actually studying Chanakya's writings (their sweep is magisterial), the following are recommended;

* The First Great Political Realist: Kautilya and His Arthashastra by Roger Boesche - A very good (and short) overview of the Arthashastra.

* King, Governance, and Law in Ancient India: Kautilya's Arthashastra translated by Patrick Olivelle - A good modern translation of the complete Arthashastra.

* Kautilya's Arthashastra: An Intellectual Portrait: The Classical Roots of Modern Politics in India by Subrata K. Mitra and Michael Liebic - A scholarly and challenging work on the relevance and applications of the Arthashastra.
