I tried for months to make it through this and I just can't do it. I don't like Rin, and I don't dislike her in an interesting way. The plot feels meandering and I don't want to read a book where I'm just trying to make it through. 

My understanding is that the arc of the trilogy is about how someone becomes terrible and willing to commit atrocities after having experienced them herself, but apparently that's not actually a story I want to read right now.
