This is a beautifully written book full of wonderful prose and striking imagery. I have never found second-person POV quite so chilling, and the fact that it is only interspersed and not the only method of storytelling gave it that much more power. I enjoyed seeing the variety of characters and the expansion of the story. The exploration of characters and humanity raises a multitude of questions in the reader. It is this emphasis that also leads to what will likely be a frustration for many readers: this is not a book interested in giving all of the answers. There are some things that are unknowable, especially in regards to Area X. We do get some answers, and they are satisfying in their own right, but there are plenty that I am sure I missed somewhere and plenty more that I am sure are not there to be found. This is a fitting end to a chilling mystery that is both unsettling and introspective.
