Rating any short story collection is difficult, but this one more so than most I've read simply due to the un-evenness of the quality of the stories.
At least 2/3 of the page count is made up of half dozen semi-connected stories exploring a post-apocalyptic world where humans thrive via uploaded consciousness and the Earth returns to an Edenic state. These stories are fine but they (accidentally?) acted as a distracting center of gravity. Was this collection meant to dwell so much on that theme? Given the title story, which didn't fall into that arch, I would assume not.
The second-to-last story, The Message, was incredible. As good as many in Liu's incredible Paper Menagerie collection. Ghost Days and The Hidden Girl were also very good.
