While I enjoy the odd bit of erotica from time to time, I don't often review it, probably for the same reason most people don't—embarrassment. But then I realized something: I shouldn't feel ashamed to read something that celebrates sex and pleasure, especially when I consider myself such a sex-positive person. High time we as a society push past that prudishness, I think.
Full disclosure: This is my first time reading anything involving domination or submission. That said, I thought it was handled well and I appreciated the realism of possible discomfort and the need to use lubrication, even though these involved mythical creatures. The relationship between Nera and Ciersten involved consent, warmth, and trust which made it more enjoyable for me to read since too often in erotica there exists some antagonistic undercurrent to the hero and heroine's relationship (which is not really my jam).
As a fan of SFF, I also liked the hints of world-building; the author provides just enough within the context of such a short piece of fiction to convince you of the setting in which these characters live out their lives. I did notice a few grammatical issues that made the prose clunky at times, but that's really my only complaint.
If you're looking to dip your toes into BDSM, this is not a bad place to start.
