Oof. I don't know. I wish this book was either much longer--so we could really delve deeper into these characters and themes, or much shorter. But as it was there was a lot of repetition for me without a ton of payoff for it.  But there were a lot of things I loved about it:
1. Structurally, this book is really interesting. It goes back and forth between letters from the psychologist that's working Dorothy's case and reactions from people in the town. 
2. Without giving any spoilers, there were a few twists that I found really interesting and satisfying (and one in particular that I found to be kind of a bummer and confusing). 

In the afterward, they talked about how the author was writing this to draw a parallel between the 1800's and now and how conservative people are enemies of free thinking and progress. I actually think that I liked the book more before I knew that. But all-in-all, it was a good story that brought me out of my reading rut.
