Well, Amazon have duly done their bit and this short story is now on sale on Amazon .co.uk and .com, though not so far as I can tell on the other international sites. Links are:
Feeling truly geeky, I also started preparing the epub files for uploading to other ebook vendor sites once the Amazon KDP Select exclusive period is over. This turned out to be more of a trial than I had expected. First go – just use the auto-convert feature in the excellent Calibre program. But that turned out to mess up all of the contents links. So I turned to the internet, and the first web page I looked at was breezily confident. Seemingly, all you had to do was put files in the right folders, use the same metadata specification file as you had with kindle, add a couple of extra config files, and compress the result. Well, the steps were easy, but the result omitted the cover art and had a number of other annoyances. Eventually I solved the problem with the help of a handy tool called Sigil which did a nice job of disentangling the various bits and pieces. A few tests on various epub apps were (broadly) successful so now I have the basic principles OK. When epub distribution time comes I feel in a much better place now than I did last night.
Talking of being geeky, my next plan is to add a timeline feature to the Kephrath site to clarify when the different bits occur, and what was happening in terms of near eastern history…
