I haven't read many anthologies based on a relatively fully-fleshed concept decided on at the start, but I really thought the coherency of the stories made this a solid examination of future cities couched in a number of very solid and interesting tales from these various artists. We've got the bio-revolutions, MMORPG economies and espionage, and even a little bit of ethical examinations. It is very much in tune with the modern speculations in speculative fiction and is lovely to behold. I've really got a sweet tooth for the sub-genre, thanks to Windup Girl, Reamde, Rule 34, a lot of Greg Bear's stuff, to name a few. This is only in audiobook format and has many of the great names reading each short story. Very good production, including most of the cast of ST:TNG for you fanboys out there.
