I’m sure I’ve mention this on this blog/website before. I’m also sure that it’s been a good long time since I did so.
I have a page on Authorgraph. That’s a website that allows readers and fans to buy e-book, and have them autographed digitally for free. Find my Authorgraph page here. I have “Quintana Roo, Yucatan”, “Quagmire Fen”, and “Hidden Tribe” listed on the site currently.
