It's about a group of metahumans/powereds working for the CIA to keep tabs on, and occasionally, kill superheroes. It'd been done through the DC Wildstorm imprint but DiDio and co got a little squeamish about how much anti hero sentiment there was in there and put the kibosh on it. Dynamite, one of my favorite newer companies, picked it up and ran with it. It's a solid book, not as good as Preacher in my opinion, but few comics so far have been. Worth taking a look.
