I picked this up a couple of years ago when I read a review of it on the Booker Prize longlist. It was of interest because I'd spent some time in the part of the world where it was set. I loved the whole story (even all the martial art stuff), and recommended it to my RL book group, and even DH! When you've read it, I need to ask what you understood by a certain part of it. People who have read it have been split 50/50.
It's the only book the author has written. Enjoy.
