I just finished this book. Most of the stories, including Buckell's, were quite good and the EOTW scenarios were varied and creative. The only drawback is that many of the stories will carry through to the second and third volumes in the series, meaning we have to wait a whole year (per the publishing schedule) to see how they they turn out.
Having short stories carry over from one anthology volume to another is a pretty unique idea, however. Hats off to Hugh Howey and SF/Horror anthology master JJ Adams for putting this project together,
