The book is really very grim, yet has plenty of depth and complexity; both Seth's recollections and the place he's in now are pretty bleak. There are flashes of dark humor now and then, but that's about it. All considered, I thought the story was very enjoyable and thought-provoking, and well worth a read. The writing quality is really top-notch and there is never a dull scene. It makes you want to keep reading and reading and reading. I would recommend this to anyone, especially those who like sci-fi, post apocalyptic books. and ponder what might come after.
