Boy, Snow, Bird started off strong, but completely fell apart at the end. This was especially disappointing because there was so much worldbuilding all through the book that seemed to be leading up to something great, but the payoff just wasn't there. The twist ending was intended to be shocking, but it was mostly nonsensical (and a little bit icky). I'm giving this 3 stars for beautiful prose and a compelling setup, and I would definitely read other books by this author, but Boy, Snow, Bird didn't do it for me.
