This is to report that because I have uploaded a corrected file to the printers it will take maybe 14 days for the Booksurge site to offer this book. However I have (the last!) 15 or so copies of the first printing available from me at £13 + P&P and I expect UK printed copies of the new version fairly soon at £17 +P&P.
