Who is reading my book before I have even seen it?

On Thursday 20 September, my publisher Troubador posted copies of 'Lauragais' to my first customers. I won't receive my personal stock until next Tuesday or Wednesday, and I can't help wondering who may be reading my book before I have even seen it!

​OK, I've looked at proofs, and corrected them endlessly, but it's not quite the same thing...
