THE BEST(this and BERLIN) indie comic coming out right now. A single issue is worth DC's whole line.
It's too bad but one part of the story, and one of the best parts, isn't yet available in the trades(and buy the trades, now. Period. You'll love them, which is the story of the house of Atreus itself in the Special, which you can probably find cheap on Ebay. It's quite different from the series--more mythological in tone. And it's truly fucking horrifying.
