Highly enjoyable! I found this via a rec for a fanwork on Dreamwidth, of all things. I've always had a love of "consentacles" and excellent worldbuilding, and this book delivers on both! The romantic tension was extremely well done, and the follow-through, very nice.
This is a sci-fi setting with erotic samesex interspecies romance. If I were tagging on AO3 I might include: enthusiastic consent, murder, casefic, interspecies relationships, consentacles, and HEA. If this sounds like your jam, go for it!
