This a story that gets bogged down in narrative feature creep. By which I mean a pretty simple story gets burdened with too much worldbuilding - so you have one element of worldbuilding, on which another element is built, but to make that work yet another element is stuck on, and so on. And what actually happens is that the structure starts to buckle, and countless logical phallacies have appeared in the narrative and the worldbuilding. The whole effect is of a writer losing control of their narrative.
A dystopian story works best when kept simple. Here we get too many characters, too much need for plot exposition (the thing where characters explain their world to eachother, which makes little sense). There is a neat thread in the story where our main character secretly learns to read, which is forbidden for her caste, and her literacy leads to her learning what is actually happening. But it's done in such an unsubtle, clunky way - she literally reads files with all those secrets in one sitting, and then spends the rest of the book telling other characters what she's read, one endless fount of exposition.
In many ways the story is a classic paranoia thriller (a genre which I love) - our main character starts noticing how things are off, and starts looking for answers she's not supposed to know. Except here, again, there isn't a clear inciting incident for her to start thinking there's something wrong, she basically has these thoughts because the plot needs to get moving. There is no build of dread, and when you have 170+ pages, that seems like a wasted opportunity.
The book has a twist at the end, and it makes no sense. I finished the book, and literally sat there for five minutes, saying "what?" out loud. I have so many questions about how this world is supposed to work, or why it works that way, because it makes little or no sense.
The art swivels madly between quite detailed and barely comprehensible - my advance copy is missing most of the colouring, which has an effect on legibility, that should be fixed in the completed book.
