I've just noticed something very strange.
I was pleased to see that the UK amazon has now listed the US edition of my book. This is not the thing that is strange; they do that with lots of books. What is odd is that somebody claims to have a used copy for sale. This is impossible - not only is the US edition not published until June 1st, but the book hasn't even been printed yet. At the moment, no copies exist.
The other strange thing is that whoever has this non-existant book is charging a whopping 38.95 for it. What would happen if I ordered it? I don't encourage anybody to risk that. Wait until the real thing is published.
You can investigate the mystery for yourself here. If you find out, please tell me what's going on!
