Shantaram: A Novel
By Gregory David RobertsIn my opinion this could be the most amazing book you've ever read. If you haven't heard about it yet, trust me, you will. I can't begin to describe the thoughts and emotions it brings up in me, especially after traveling to India.

If will take you a while to get through all 900 pages, but I can almost guarantee your life will be different because you took the time to read it.
