On her blog, Faith Erin Hicks shared some Supergirl drawings that she describes as being for a project that never got off the ground. She was never told the fate of the comic/cartoon/pajamas/whatever-it-was, but guesses it's not happening because "generally when you don’t hear back about something for a year and a half, the project’s probably dead."

I'm guessing that the New 52 is what got in the way, but regardless, it's too bad. Whatever it was, I would have wanted it.
