2 stars probably seems like a harsh rating, considering that there's nothing particularly wrong with this book at all. It's just that it had a really hard time holding my attention and I basically spent its second half just waiting for it to finish (I'm not good at dropping books halfway through, unless they're really terrible, which this isn't).

So what's up?
First of all, I did not really care much about the couple at the center of this space romance: It's a classic pairing of ditzy sunshine (a nerdy version) and quiet, unreadable, overly muscular man hunk way too concerned with his honour. The PoV character Kee (the sunshine) is not uncompelling, but I generally found it hard to connect with and get invested in any of the main characters in the book - they're all just a little too perfect somehow. The way they are a chosen family is cute and great to see overall, but I found a lot of those scenes cheesy, and those where they constantly tease each other about their sex life in the middle of a space drama were really cringe.
The central conflict keeping the couple apart in the later 2/3s of the book is a stupid personal honour thing on the part of the male MC - it's made very clear that it's an alien cultural norm, but since the aliens in question are invented by a human author, I still don't care for them.
I love a fluffy, sweet romance, but that vibe did not fit for this particular pairing, nor with the dramatic sci-fi story making up the rest of the book.
I also found the sex scene at the end pretty cringe.

So overall, not for me. I thought I'd really like it, but I didn't - but your mileage may vary!
This definitely feels like it's just not for me. I've just recently read a different space romance (Ocean's Echo) with telepathic communication which just grabbed me so much more - higher stakes, compelling characters with depth, the mental connection being far more emotionally interesting... This one really didn't measure up in comparison.
