I always sit straight down and read these volumes in one sitting. And then it struck me... they're just not long enough. I almost wish I hadn't discovered them when I did, because the wait between publications is nearly unbearable. 
 First off, a warning: For mature audiences only. There is nudity, language, violence, drug use, and probably a bunch of other stuff that I'm not including. For me, all these things simply add to the already brilliant story. 
 I think Fiona Staples could easily be my favourite illustrator. I would be tempted to have some of these pages as full sized posters (if I didn't have kids, with delicate sensibilities).
