To be fair, I didn't really expect much from this book. So it's not like it didn't deliver, but more like it was pretty much what I thought it would be. It ran its fairly predictable course, and it's not like it wasn't entertaining, but it was also not ever very gripping. 
 The narrative kept insisting that the stakes were high, but never actually delivered anything particularly shocking. So I never really believed anyone important was really in danger. 
 And it felt a little like Divergent-lite at times, what with the controlling of society but of course it doesn't work on our protagonist, etc etc etc. (Which, it's not like that's a bad thing necessarily, because as a plot device it can be fairly intriguing, but the execution and pacing didn't work for me.) 
 This is definitely a book driven by its plot and not its characters. There isn't a lot of time spent developing anyone and they all felt flat and two-dimensional. So, as a result I didn't really care about anyone. There's one mildly surprising character death at the end that didn't make me feel anything, which is kind of a big deal because it is super easy to make me cry. 
 I'd probably skip this one to be honest, unless it really sounds like your thing.
