Have you ever read a book that was written in such a way that you felt it was contemporary, although it may have been written and published long before? Along the same lines: Did you ever read a contemporary book that was written in a way that made it nearly impossible to tell what era it was set in?

For me, I found Snow Crash, by Neal Stephenson to have incredible foresight.  It was written between 1989 and 1992, but the description of the "metaverse" is EERILY prophetic.  There were a few little hints here and that would have hinted to the actual time the book was written in, but it was a fun challenge to catch them. 

Mary McGarry Morris'  A Dangerous Woman seemed nearly impossible to figure out.  It could have been set anywhere from the late 70s to the late 90s.  Anyone ever read it?

One that I found hard to pin a timeframe on was "The Thirteenth Tale" by Diane Satterfield.  It was brilliant though.

I've not read either of the ones you mentioned.
