I do love a book with multiple story lines that seem totally unconnected until the last two or so chapters. I love books like that a lot. Gibson pulls his complicated plot off well. I'm not convinced that future generations will connect as strongly to the explicitly 'oughties' technology references as I did, but Spook Country will make a heck of a period piece in a few decades. Good stuff!
Also, dude is a friggin' tweeting machine. I had to stop following him because he fully dominated my feed every single evening. Check him out if you dare! @GreatDismal
