Aquiver

Dealing with Drow nobility had never been Khouri Lucifin's strong suit. Strange, entitled, overwhelming, untrustworthy- There was no end to their unsavory habits, and when one was a street dwelling, half-Drow thief, dealing with them was a risk that didn't need to be taken.
But when Khouri is contacted by a noble wishing to hire him for a mysterious job, he finds the promise of wealth untold too enticing to refuse. There's just one catch. The job in question doesn't call for the skills of a thief, but those of an assassin, and the target isn't just any Drow, but a noble by the name of Lord Navidae Marrowick.
Risk follows Khouri when he accepts. Marrowick, he finds, is far harder to kill than first expected, and far more pervasive than his employer had led him to believe. Navidae has everything Khouri doesn't, and when he catches Khouri mid-assassination, he responds in a way Khouri simply has no defense against. Succumbing to his mark's charms is easy, but dealing with the fallout is something Khouri never anticipated.
Dominance, submission, deception, and violence- Just another day in the Duskriven, and this time Khouri is determined to get what he wants, nobility be damned.
Prequel to Epithymy, can be read as a stand alone novel
