Out of Print
Since they invited me to ring them if I had a query, I did. A moment of puzzlement followed, eventually solved when it was realised my books were all out of print and so have been eliminated from their database.
It is a sad reality for an author today, especially one of the literary fiction variety, that a book is in print for a far shorter time than it takes to write (and in my case research).
However, the sun is shining and I refuse to be downhearted. My books had their day, and maybe my new novel will have its day too. The important thing is to not look back and keep going (and maybe try to persuade my publishers to look into print on demand).
And lovereading is a very good website....
