After a long wait, my books are once again available in the Sony Reader store. You can find them here.
Also, I've recently started distributing to the Google Play store. There are some awesome Google tablets available now, including the Nexus 7, and I suspect a bunch more coming toward the end of the month. As of today, only the Elements of the Undead books are showing up. I expect The Patriot Paradox and Pressed to go live in the next several days.
Which brings up a good question. What do I use to read? I split my time about 80/10/10 between a Kindle Touch, a rooted (means I can install the latest and greatest Android versions) Samsung GalaxyTab 10.1 running CyanogenMod 9 , and a Samsung Galaxy Nexus smartphone. I love them all.
