I confess that audiobooks, as opposed to plays, don't always work for me. Each of these five stories is of the order of two hours in length, so not well suited to the concentration span I normally have while commuting. In addition, I found the voice registers of three of the actors doing the readings (Michael Hogan, Scott Brick and Stefan Rudnicki) too low to really hear distinctly over the bacground noise of my train journey. This isn't usually a problem for me listening to Big Finish or Shakespeare productions with numerous actors playing different parts. I therefore didn't really take in much of the stories by Jay Lake, Tobias Buckell and Karl Schroeder, though I liked what I could hear.
The basic concept of the shared world, set in a near future where state structures have collapsed and cities per se have become largely autonomous political actors, combined with a somewhat sinister worldwide culture of game-playing which mixes geocaching with Diplomacy, is a great idea. Unfortunately I can't really render a judgement as to how well it was executed.
Having said that, I enjoyed the two stories I was able to hear clearly - Elizabeth Bear's "The Red in the Sky is Our Blood", read by Kandyse McClure, and in particular John Scalzi's "Utere Nihil...", a rather charming coming-of-age story in the comedic cyberpunk thriller mode, read very effectively by Alessandro Juliani, which to me stood out as the gem of the collection.
