At first I was kind of annoyed because the author puts you inside the head of the exact character whose head you don't want to be in. The story got more complex and engaging, though, so the annoying main character was easier to handle. It was weird having a feeling like you have to root for the main character because the perspective is narrated that way but also rooting for her failure because of what she did.
