Diversify!
To avoid putting all my eggs in one basket, or all my books in one distributer, I have joined Smashwords. While I haven’t spent much time on this site, it is clearly very supportive of indie-authors and grassroots projects. If you’re looking for a format that isn’t supported by Amazon, you can find God Strain on Smashwords.com.

My friend advised that I jump on Smashwords as well, even though it’s another electronic medium, because it’s a more welcoming market. The site is more difficult to navigate than Amazon, but that’s the nature of the beast.
I’m currently working on a paperback cover for a real, in-your-hands edition of my first book.
Thank you to everyone who has purchased and supported my work thus far. You’re the reason I’m pushing my writing to the next level.
