Realm of Racket is such a strange book. It feels like they tried really hard to follow LOL or "why's (poignant) Guide to Ruby" aesthetics/structure, with mixed results.

Also, I know this is silly but I remember the book followed this guy who was supposed to be "the hero" that was always sad or concerned, or frowning, in every picture, right on to the end of the book (or so I remember it...). I know it is silly but that put me down :-p
