I'm pretty sure I read this when it came out, and I'm choosing not to reread.
Literally the first comic after the introduction makes casual use of the r-word. I found myself sitting there for a few seconds wondering if 2013 is so long ago that a person (and their editor, and their publisher...) wouldn't know better than to do that. I'm not convinced. My "to-read" list is gigantic so I'm just going to move along.
