I also noted that they don't mention the paperback version of The Children's Book of Richard III. The hardback copies have completely sold out which means that anyone visiting Amazon to get a new copy of my book, rather than a used copy, can't get one. I don't know what Amazon's rules are but I have stated as much in my author profile blurb. Here is what I said:
...Rosalind's 'Children's Book of Richard III' is selling so well that it has now gone into paperback. The paperback does not seem to be available on this site but has proved to be a best seller in the Richard III Visitor Centre, Leicester's Museum shops, the Bosworth Battlefield shop and can be purchased from the author herself...
I wonder if they will object. Incidentally, I now have a supply of books to sell at events etc so if you would like a copy, seeing as you're my blog friend, I'll let you have a signed copy for £8. Just comment below.
This is the link to my Amazon author page. If you've got a browsing minute perhaps you could have a look and let me know if I've missed anything or if anything needs updating.
