The character work in this book is fantastic. Cass has relatable motives and attitudes and all of her actions feel very understandable and sensical. The pressure applied on her by the plot all feels natural. The secondary characters are also all fantastic; I especially love how the culture divide between Meridian and Loyala is set up and portrayed. Grandam is a great source of personal antagonism, Cass' relationship with Andie is so sweet, and the romance with Rollie is cute. Day is also a powerful villain, even if she's somewhat predicable/cliche in my mind.

Stemming from Day's cliche role, the entire plot structure of the book feels rather predictable to me, too, which would be one of my bigger critiques. At the same time, though, if you like stories about a talented underdog who feels trapped by the machinations of an evil corporation, well... this narrative structure is popular for a reason. This is an excellent delivery of this common premise. I would say that the worldbuilding does add just enough newness into the equation that I wouldn't harp too much on this point--I'm very fascinated by the setting that's just far enough in the future to give rise to foreign cultural components and technologies while still being close enought to today's world that I can easily see where these parts of the culture came from.
