Two words—Holy Shit!
I wrote a column about it for City Weekly the other day, so hopefully that will show up in next week's issue (and it's much more eloquently written than "holy shit," I assure you). Do yourself a favor and pick it up ASAP. Jason Aaron is making his mark on the Vertigo line the same way Ellis did with Transmetropolitan, Ennis did with Preacher and Azzarello did with 100 Bullets—all books you should read, by the way.
Here's the cover for Januarys issue #35. So awesome.
