I have not turned off anon. I presume Tumblr is “being weird”.
The books will be available to purchase from all the usual media stores. The publisher is small press, which means they do what is called POD or Print on Demand, which does tend to come from a central location. If you find the books too expensive, you can contact me, and I can see what may be possible. Obviously I cannot offer this to everyone forever, but we will see.
You can also enter any of my contests and win free copies. I do several per year, all giving out free books.
