Ava breaks Shane out of prison at the very start, then, with a few different configurations of crew members, they pull off a series of heists to get supplies to their families and hopefully mess things up for the military exploiting their planet. Cyrus is a member of that military, newly graduated and ready to climb the hierarchy. When he runs into the outlaws it complicates his worldview and he starts to think his commander might not be dealing fairly with their planet.

I was just familiar enough with Bonnie and Clyde as an idea that I came into this prepared for major character death, and it's a good thing I was ready. This is the kind of story where all of the characters are fascinating but I didn't particularly think any of the main characters were unambiguously the good guys. My anchor amidst the ambiguous characterization is that someone gradually emerges as a definitive antagonist to the cluster of antiheroes. 

Cyrus hits me oddly in the trio of protagonists. I'm wary of books which expect me to sympathize with the cop character, but this ends up playing out closer to "everything sucks, there are few right answers, but supporting this system is definitely the wrong answer." There's a way that Ava and Shane are treated as protagonists which I don't come across very often, but I generally appreciate. They're antiheroes, reactive and tactical, with some plans but not a great sense of strategy. Each of their moves is based on it being better than the previous move, but they're young, don't have very much support, and the way that they've ended up as outlaws feels very impulsive. When they stumble upon away and make a bigger impact they don't quite know if even this will work or do anything. They're socially isolated (partly by choice) from the society of their backwater planet, seeing their families only every few months between jobs. Their parents are doing their best in a system where existence is a slow demise, and there's a hopelessness which Ava and Shane have honed into desperation.
