It's the little things
Sometimes, when you're reading a book set in another country, it's the little things that you notice the most. For instance, I'm reading "Brittle Shadows", a novel set in Australia by an Australian. This sentence really struck me:
[She was] wondering what it would take to convince her dour-faced taxi driver to adjust the air conditioning to something less than Antarctic.Antarctic?
Well, sure. That's what they're next to, after all.
But I doubt it would ever have occurred to me to put that word in if I were writing an Australian character...
