Damn it. I knew this was coming, because SYNERGY! And I didn't want to read it, because I don't really care about the Eternals.
But Gillen makes this a must buy. Some of his Marvel stuff hasn't been as good (I'm looking at you, Iron Man), but when he's on his game he's one of the best in comics. And he does high concept stuff better than almost anybody around these days. I'm not expecting another Wicked + Divine out of this. But if it's even Young Avengers good it'll be more than worth reading.
