This is a very sweet sci-fi romance that hits all the right notes.
It has an interesting world, an earth not that far into our future, with extinct polar bears and tiny ice caps and all of our human frailties and human disregard for our own planet - it paints an Earth that is still full of all our modern conveniences, but there is one slight difference... Aliens.
They came to Earth, and end up in a situation not unlike the massive films District 13 and the amazing novel by R. Lee Smith, Cottonwood, with travel restrictions and lots and lots of xenophobia.
You'd think this would paint a bleak picture, but it doesn't. It remains full of love and hope for our essential selves, and champions inclusivity and being the best soul, be it human or alien, that you can be.
All of this, in a relatively short little novel. It also throws in a sinister plot involving kidnapped aliens and a ptsd ridden veteran-turned-lawyer who fights his fears of the aliens by trying to solve this mystery, and falling in love along the way.
Lots of boxes are ticked - lgbt and intersex aliens, inclusivity, a number of PoC characters and some heartfelt and truly hot lovemaking.
What's not to like?!

There are a few editing issues - a number of typos, such as has or as instead of was, but they do not detract from the story.
My criticism would come in the form of one) the length! I wanted this to be muuuch longer so I could better enjoy it - I'm a sucker for slow burns! But that's only a gripe as I prefer giant chunky books.
Having a short novel means it felt a little rushed (and seemed to take place over the course of a few weeks rather than months that I would have preferred), and sometimes the pacing of the love story also felt very fast.

But these are not deal breakers, and I sat and happily devoured this book and would buy it (or more like it from the author) for sure.
Recommended to sci-fi fans that love romance, especially queer sci-fi fans that love alien/human pairings.
