This was almost flawless. Not only does it have a good story and great characters, but served as an interesting insight into cultural influence of a great empire onto small ones - from the PoV of someone from the small one. That rings relevant for many of us here in central Europe. The emphasis on language and custom as a way of shining light onto a clash of cultures was also very well done.
And Amy Landon's narration was unbelievably brilliant. Haven't heard its like in ages. I'll have to look up more books she narrated.
