After much swearing at Amazon's KDP editing tools and a few aborted attempts, finally, I have a print copy! It is available here for £9.99 (or whatever the equivalent in your native Amazon). Plans are afoot to see if I can sell the book in other marketplaces; if you've any suggestions then I am happy to hear them, as frankly, I've still not got a clue how bookselling works or what's good, so all input is good at this point.
Now that I have a physical product I feel the need to buy a coffee table to leave it on. That's not wanky, right?
