Liked it a lot. Maybe part of the charm was the setting, I really felt like I was getting a window into a different country's way of life and thought. Also it was a pretty tightly plotted mystery/thriller, with lots of fun wealthy family excesses and mistrust and some loonie religio political madness thrown in for extra spice.
Like others I enjoyed the central characters a lot, actually all the characters. And the translation was good, gave me what I needed to understand the story without getting too much in my face with explaining the cultural context.
