4.5 stars. 
 Holy smokes, I didn't actually mean to finish this all tonight but I hit that sweet spot and just couldn't stop. I am trying to resist the urge to order books 2 & 3 immediately because I am trying not to buy a ton of books right now BUT. 
 Wow, this was a lot of fun. Like, just really good sci-fi fun. Devi is a fantastic narrator, but all the characters were great. And Bach does something really cool with an alien species and their approach to gender which I ADORED. And oh man there are some huge freaking secrets going on here and some of the dialogue in the last few scenes really started to tease out hints of a much larger world and I am just SO IN. And AH that ending. AH. 
 I had a feeling I was going to like this, but I didn't expect to like it THIS much. If you like spaceship/mission centred sci-fi, mercenaries and kickass lady-types, you should probably pick this up immediately.
