Sales are increasing as more people talk about the book. . . plus, I am sending out postcards with an image of the cover art to selected friends I don't meet and greet on Facebook or through regular email. I am especially sending the cards to family friends, some of them who may not be using the Internet as much as others do.
It seems to be helping sales, and without a big publishing house behind us, all we can do is put our own ideas to work.
