If only sales on downpour were possible outside the US. I just tried to buy a K. J. Parker. Does not sell to the EU. I haven't tested libro.fm because their ToS doesn't tell me if non-US sales are prohibited and I'm not going to make an account just to try.

Hmm, I'm in the US, but this page would seem to at least indicate libro.fm at least supports multiple countries? I don't know what the selection is like though. https://support.libro.fm/support/solutions/articles/48001183...
