Ok, so the Kindle version of my novella is now up on Amazon.
The Amazon website seems to have resized the cover, thereby losing part of the border, which I will try to rectify as soon as I can. If anyone would like a free review copy, please email me at alanmcampbell at gmail dot com, and I'll send you one.
I'll now see about creating an ePub version.
Thanks to everyone who offered advice and help. And congratulations to Will and Kate!
