Hiya,
This is the author - thanks for your interest!
Elerond is right - it's up on amazon.co.uk, and that's probably your best bet. I recently made a fix to the cover, which might be why they seem to have a limited stock available - it should (in theory) be back fully in stock within a few days.
You can find it on Barnes and Noble's website, too, but I'm not sure if they have any copies out in Europe.
