Bread and Milk and Salt

I like how Gailey writes, I think they give life to their stories in a way a true writer can. I've only read two short stories by them now, but I've liked enough of what I've seen to want to read a full-length novel. This one is a dark fantasy and it honestly hurts my heart to read about the animal testing and what Peter does to our protagonist mid-way through the story. Those things have always been close to me emotionally and led me to want to witch-hunt Peter.

- What animal would you change into if you could?
