Nope! They're about superheroes. There's a limited edition hardcover out of a first volume of the stories that I think is also available as an ebook? (Yep.) But I read them all on her lj. (Her site also has some of them in easily readable order.)

They're short stories and the setting is really cool and oh my god they are SOUL-DESTROYING. I LOVE THEM SO MUCH I keep trying to get my best friend to get around to reading them so I can flail about them at him properly. (To be fair, he's already read all of Newsflesh because of me, and is currently reading Cat Valente's Deathless because of me, so. >_>)
