Two of my books are available from an e-publisher called Untreed Reads. They made available the e-version of Threatened Species (a novella and five stories): here
Also, they published the e-version (and only version) of my futuristic novella, Parable of Weeds.

You can order directly from Untreed Reads, and they make the books available in many formats, including simply having the book sent to your computer as a PDF.
