I'm surprised that I sell more books in Cambodia than the UK

As an author do you ever wonder where your books are being sold? Mine are exclusively sold online through Amazon, Barnes and Noble, iTunes, etc. However, a lot of paperbacks get sold and end up in second-hand stores which we cannot monitor.

I was just reviewing my publishers report tonight for the first quarter of 2014. These countries include not just my books, but my partner Bernard DeLeo's action/adventure books also:

United States 36.42%
Canada 11.44%

China 9.92%

Australia 8.24%
France 4.50%
Cambodia 3.54%

Brazil 3.13%
United Kingdom 2.86%
Ukraine 2.41%
Germany 2.05%
Russia 1.94%
Israel 1.67%

These are the top 12. It goes on to list over 90 countries.
