I find it interesting that most of the books that I enjoy the most in the “Science Fiction” category are really not “Science Fiction” at all.  I’ve really enjoyed reading Zero History by William Gibson (not quite done yet!) and the other two books in the series.  While the publisher marks them as SF, they clearly aren’t.  There’s nothing really speculative about these books from a science perspective.  It reminds me of Cryptonomicon by Neal Stephenson, also categorized as SF but really just high-tech fiction.  And so my question is — who and what else should I be reading that falls in this category?  These aren’t quite suspense or spy novels, but they really resonate with me.
