A lot of wasted potential.
I don't read a lot of sci-fi romance, and this particular work felt heavy on the sci-fi/politicking and light on the actual romance, but that imbalance may be actually just a different balance than I'm used to because of the subgenre. Sci-fi takes a lot more world-building space than contemporary or military or half a dozen other subgenres, so this criticism could fall under "it's not the book, it's me and my faulty expectations." I honestly don't know.
What I do know is that the world-building here is full of holes, starting with the time period it's set in. This was published in 2016 and set in 2036. That's twenty years out, yet apparently Earth has colonized another planet, and we've been there for at least a while, presumably longer than twenty years, based on the level of devastation we've inflicted on the native population, and the fact that the lead's grandfather was a political agitator in the past about the colonization. (If there were hard dates given to the timeline, I honestly don't remember them, but this didn't feel "new" as it was happening, it felt like they'd been at this a while.)
So am I supposed to believe this is our Earth, our society that's doing this? Because we're not. This isn't set far enough in the future to be a believable course of events, and if it's supposed to rely on some alternate history where the story Earth diverged somewhere in the past and this is their future, that alternate history is not given.
Okay, so my brain pushed it farther into the future to get past that, because hey, does it really matter? It's just a year number, right?
But the holes just keep coming. The native population was brutally crushed under the weight of colonial boots, apparently, but the fugitive men we meet and who become the protagonist's lovers have a surprisingly deep awareness of some aspects of human history and culture, odd things that my brain kept bumping into and saying "How would they know this? What human taught them this?" And they know English and some German (apparently, it comes up once and is never mentioned again) but I never saw any evidence of the sort of formal schooling that would teach them that (they're really fluent, this isn't a "pick up it from the oppressors while I'm fighting to survive" kind of knowledge) and it's all just hand-waved.
Then, let's talk about the "romance." I have never read any romance novel where consent is so unclear. Courtney really just does sort of fall into bed with one of the men, and yes, we the reader know he's sick because of a hormonal imbalance that female pheromones will alleviate and eventually cure, so we know why he wants to bang her. But she never really says yes, and during that first scene and several following it, Courtney asks him (or later, the other man in their pairing) "What are we doing?"
It keeps happening, this bewildering sex they have without any sort of discussion or boundary-setting or even emotional attachment. It's strange and uncomfortable and not particularly sexy to read, because I was as bewildered as Courtney. Yes, it's established she finds both of them attractive physically, but there's never really much of an emotional connection, and at one point Courtney even questions if it's appropriate for her to "use" Murk for sex because she's a colonizer and he's a native. Which, yeah, dicey dynamic there.
But I called this wasted potential because the bones of a good setup were there. I wanted to read a story where these two men were suffering doubt about their attraction to Courtney: is it just their biology, are they that desperate for pheromones, or is it something beyond that? Could it be real? And I think that might be what the author was going for, but I never thought she got there. An unplanned (and supposedly impossible) pregnancy happens instead, so suddenly they're all stuck together whether their relationship would have developed naturally or not, because (newsflash) the dominant male partner in Jekhian trios are biologically baby-crazy and territorial as all get-out.
There were moments, when the three of them were trying to hash out their cultural differences and what it meant for their expectations of relationship and family dynamics, that I keenly felt that wasted potential. This could have been so, so good, if it hadn't fallen into the baby trap as a shortcut to keeping them together, if it had explored the power balance among them with any kind of nuance, if it hadn't relied on keeping one character mute for most of the book because he was the one who could have explained Jekhan culture better than the one who could speak, which fueled constant and repetitive misunderstandings. (Side note: that muteness was handled poorly, which couple with a great deal of head-hopping, meant that a lot of times I honestly wasn't sure who was speaking/thinking any given line. So that was no fun and did not help matters any.)
I did not like this book at all, but I'm left with a wanting feeling to read the book it could have been, because I think I really would like it.
