I prefer the paperback. I like to turn real pages and smell the ink, thanks! Just tell me where I can get them, please. ;o]
Best place, I think, would be Barnes and Noble, using the pen name Brian B. Hawthorne. You might be able to get free shipping or arrange pickup at your local store.
Cautionary statement: I’m calling some of these books a treatise on social behaviors masquerading as a sex book.
Sociological science fiction — yeah, that’s it.
