This book is so much better and more interesting than its title and cover suggest. They suggest a cheesy alien abduction/fated mate smut-fest (not that there is anything wrong with that when you are in the mood!) but it is so much more awesome than that.
The aliens are really alien in their thinking and actions. Liam has been living and working with them for years, and there is still much he doesn't understand. His new (horrible) boss both understands far less about the Rownts and thinks he knows what he needs to. A shining example of the Dunning Kruger effect (where people who are ignorant think they are much smarter and more competent than they are).
Liam and Ondry have trouble understanding each other, because their cultures are so different that there are many words and concepts that don't have a direct translation.
Ondry has the advantage of basically (see below cut for spoiler) and just goes ahead and does what is both good for Liam and appropriate in Ondry's culture, though it causes a huge uproar amongst the humans.
Some spoilers and content warnings after the cut.
Spoilers and warnings: Ondry kidnaps Liam and arranges to read his mind, and figures out what Liam wants and needs - and arranges for him to have it. Liam is a natural submissive, and needs someone to dominate him and take care of him, so Ondry takes charge without any further permission (hence the dubcon warning you will see - it isn't really about sex). Because of his own cultural background (and some bad experiences with assholes who took advantage of him and abused and betrayed him), Liam can't feel good (at first) about letting Ondry do this, while Ondry feels he would be letting Liam down badly by letting him go. They need to come to an understanding before they can be happy together, but once they do, they really are made for each other.
