I just finished Spook Country. I enjoyed it, but if someone were choosing between this book and Pattern Recognition, I'd recommend the latter. If you haven't read any Gibson, then go with Neuromancer first. This is not a good place to start with him. On the BoingBoing.net podcast, Cory Doctorow referred to Spook Country (and I think he was including Pattern Recognition in this) as "radical speculative presentism." I do like the sound of that. As with other novels by Gibson, the novel starts with several seemingly unrelated characters doing seemingly unrelated things. It takes a while for the various threads to coalesce into one story. A second reading is probably worthwhile.
