Rynn, the emperor's assassin is tasked with going to Earth to bring back Lizzie Kallson (Jess's twin). He ends up having to bring along Lizzie's nurse, Jac as well. He's very tempted by this human, but doesn't believe himself to be worthy of claiming her.
I don't know that I agree with the title here because there's very little adoring going on. Rynn may claim to want Jac, but he treats her like absolute shit. First he kidnaps her, which he more or less apologizes for and there's not much he can do about it. But she takes her chance to fight back, incapacitates him and inadvertently calls for help to a purist faction of Lathar who take Jac and Rynn prisoner. Instead of trying to see things from her perspective and why she would have done what she'd done - he just gets pissed off with her and blames her for their circumstances (real nice guy). Then, he figures she owes him sex since he's not trapped on his enemy's ship. He takes what he wants, she loves every minute of it and then he treats her like crap from then on. And unfortunately, Rynn's feelings regarding the heroine's role in their capture and the death of Keris, never really gets resolved and he never really talks about it with her.
Now maybe if our heroine had been strong and gotten herself a righteous case of anger, I might have been okay with this. But she sits around near tears, cowering in a little ball and taking whatever abuse he heaps on her. And somehow she comes to realize she loves him. Does she stand up for what she wants? No. She lets him warn off all these other guys, come use her for sex at night and then not doing anything to claim her. Then, instead of standing up for herself, she sets up a little farce choosing and waits for him to come claim her. Then of course, he explains that he felt so dishonored by his own birth circumstances (being oonat born) that he didn't feel he deserved her...so that gave him the right to treat her like a piece of garbage.
Also, the whole oonat thing is pretty damn gross. If we believe this race is simliar to humans, then the Lathar are forcibly impregnating their women and taking their children away from them to be raised as Lathar. If we believe they are more similar to cows, then the Lathar are basically having sex with their livestock and getting their cows pregnant. So it's either enslavement or bestiality.
Eew.
