Ophidia Cox's author bio says she is "interested in fetishes and sex that doesn't follow the textbook's instructions." The fetishes and sex explored in this book were really not my cup of tea -- the female protagonist is a prudish novice domme who doesn't like penetrative sex, the male is an obese submissive who likes to be penetrated (front and back) rather than do the penetrating. I found most of the sex described in this book to be just... weird, and yet I liked the book itself quite a bit, because it is unlike anything else I've ever read.

Vincent (the obese sub) runs the Cyberkink Sideshow, a sex circus in a steampunky world where technology allows humans and machines to interface both professionally and, er, recreationally. Sylvia (the prudish domme) is a K9 cop assigned to go undercover at the sideshow, investigating allegations that the show is a front for a dangerous cyber-terrorism organization. Cox paid a lot of attention to world building, and that's what makes this book stand above the crowd of self-pubbed erotica.
