Sequel to The Informationist
(Not actually as violent as The Informationist, though, I thought.)
I liked this one even more than the first.
The writing has improved (though there are still a few things that really an editor should have picked up on, but whatever) and this plot interestingly explores a situation so similar to the author's own past.
And you have to love the moment when a character realizes that the seven dead bodies he's looking at were killed by the woman he's been trying to pick a fight with.
