I am temporarily unable to offer my books in Kindle form. All my Kindle files were in the .mobi format that Amazon used to prefer and promote but has now decided to no longer support. I am working to convert all my Kindle files to the ePub format that Amazon now mysteriously prefers. This will involve a bit of time , effort and expense.
When will I get this done? Well, as you know, I'm famed for my very high level of personal and professional efficiency. So, I expect I'll get round to it at some point between now and either (a) the heat death of the universe, or (b) the point at which newspapers stop running astrology columns, whichever comes first.
