If I could use any two words to describe this book, it would be these: heavy handed. Incredibly so. I should give some kudos for there being themes and a message, but the themes are so forced I really can't. I felt like I was being beaten over the head by this book every page I read, and that was not my favorite feeling.
The worldbuilding could have been good, but there was absolutely no subtlety or nuance. There are a lot of critiques for the modern school system that one can have, but this doesn't really utilize them. It's kind of the "homework bad teachers mean" type thing, which is... valid I guess, but it could have been so much better. And the villains are just... For a dystopia to work, there has to be a competent government system holding it up, and some people have to benefit enough to see it as a utopia and want to hold up the system. There are neither, so the dystopian setting kind of fails on a fundamental level.
The writing is... not good. The author is (was? This is an oldish book) young, which can excuse it not being expert level prose, but even for a teenager, it's not very good. There are enough typos that my confidence in the competence of the editor, if there was one, is not great. Virtually every sentence is awkward and wooden. The phrasing is extremely poor. The dialogue doesn't sound like people. There's an overuse of phrases (the "icy blue eyes" of one character are described somewhere between three to five times on a single page) and often the same uncommon word appears twice in the same sentence or paragraph (a character gives someone a defiant look and then their next line of dialogue is said in defiance). A lot of the book is made up of fight scenes, but aside from changes in scenery, they're basically copies of each other with different opponents. Part of the fun in fight scenes is the variance, but this doesn't have that and it just gets boring.
The plot was repetitive and dull. The beginning was supposed to be the setup of the dystopia, but it was done so badly it didn't work at all. Still, while it wasn't well done, it was the only mildly entertaining part of the book. From there, it was really just boring. It was cliché, predictable, and there didn't seem to be any progress happening. The main character was accepted way too easily and gained his skills way too fast. There was supposed to be change caused by what was going on, but it didn't feel like anything was happening. The primary villain barely did anything and the secondary villain was introduced too quickly and stopped being relevant too soon.
The characters also weren't very good. There wasn't much depth to any of them. The villain was laughably cliché, the protagonist was bland, and the secondary characters had one personality trait. I felt nothing for absolutely any of the characters. The only two with anything in the way of depth, Zyid and Umasi, were badly executed and boring. All the characters served the plot, which is odd because the plot went nowhere. There was also a very noticeable lack of female characters (there were three named ones, I believe, compared to twenty or so male characters), but that's neither here nor there.
Overall, this was a poorly written book. While it's cool to see teenage authors getting their stuff out there, but this was not a book that was worthy of being one of those. There are much better teenage authors that have written much better books. On the upside, I have a little more confidence, in my own ability as a teenage writer, but that didn't really make this worth it.
