Honestly, I was expecting alien/human PWP involving tails. In fact, most of the story seems to focus on Liam's assimilation into alien culture - misunderstandings, translations and setting ground rules for what comes out to be a d/s relationship. The world building was done well, though some things in the alien culture made me cringe or think about cheap special effects you see in old science fiction shows. But overall, this was a good read. If you're looking for a SF read about one man who falls into (literally) the nest of his one true love, who happens to be a purplish colored, flat-faced alien, then look no further!
(Note to self: I still prefer the traditional peen over a tail when it comes to my M/M sex. Too bad that's not anatomically possible here without a deja vu scene from Bloodraven).
