This one caught my eye when it popped up on a best of something related to graphic novels, and, having totally missed it when the series ran or when the graphic novel was published, my reaction was the same: gee, that's exactly the kind of thing I'd want to read during the holiday/end-of-year gift book reading binge, so I ordered it (and my spouse wrapped it ... and then, OMG, how did you know that was exactly what I wanted?!?!?!) ... and, then, of course, I read it, and...
