I'm not quite sure what words to use to describe this book. The writing is fantastically brilliant, just genius. So many of the little observations were ones that made me think "Aha! Yes, I have always felt the same way."
The story itself is just entrancing in its beautifully-told ugliness and feral strangeness. I felt almost hypnotized reading it, disgusted at some parts but weirdly craving more, and I usually like my stories to be neat and clean. Maybe I loved it because it is a neat and clean narrator telling a wild ugly story.
The big reveal at the end had me reeling, and I immediately had to run over the entire story again in my mind, putting everything and everyone back into place with this new information. Masterfully done!
