I honestly didn't know what to expect when I opened this book. There was a picture of a slightly angsty-looking teenage girl on the front cover, and since I judge books by their covers, I was skeptical. However, I love Carrie Ryan's style of writing. She emphasizes the setting so clearly that it's easy to picture oneself in the story completely. Ryan is constantly describing textures and senses and gut feelings. I almost never like stories that contain love triangles, which did occur in this book, but I enjoyed the unique zombie-apocalyptic setting, the legalistic portrayal of the Cathedral and Sisterhood (and the discovery that there might be faith in God outside of rules), and the storyline in general. This was a quick, fascinating read.
