Notable SF editor and writer John Joseph Adams takes a listen to Metatropolis and says some very nice things about it at Tor.com:
METAtropolis is one of the best anthologies I’ve read in a long time. The worldbuilding was fantastic… all of stories all examine the ecology and economics of the future, which seems eerily prescient considering the current “economic apocalypse” the U.S. is currently going through (a term actually mentioned in one of the stories).
Where the anthology succeeds best is its vivid and believable depiction of one possible future. You probably wouldn’t want to live in any of the cities depicted in METAtropolis, but you’ll surely have a blast going for a visit.
Now, disclosures: As you all know, I blog for Tor.com myself (although not so much in the last couple of weeks as I’ve been migrating this site and catching up on work). Also, Tor Books is my publisher and also publishes the other co-writers of Metatropolis. That said, Metatropolis is not a Tor project (it was released by Audible.com), and I’ve read enough JJS to know he’d take a plank to something if he felt it needed a planking, and the Tor.com would let him use its space to do it. So while I’m naturally biased on the subject, I think it’s a fair review.
Also, Audible.com had put up a ginchy Flash-based site for the project, with lots of bells and whistles, including audio excerpts and screensavers. Head over and waste some time there.
