I went to read this because I recognized Jennifer Egan's name. The associations in my head for her name were 'award-winning, literary, sci fi'. The story is interesting but I don't feel that I fully understand it.
When I checked my journal database I found that I'd read her book _The Keep_ in 2011 and been impressed. Similar to this story, though, I was more impressed while reading it than at the end, where there were some things that seemed unfinished.
