This grade reflects a strong bifurcation between the book's aesthetic & coloring, which is as potent and lovely and beautiful as anything can be (and exactly what I expected from my fond memories of reading On A Sunbeam) and the plot, which, uh, less so. There were some redeeming bits here: the central characters are roman a clef ciphers but pleasant ones; the Office of Road Inquiry (and faint feline mysticism); the shadows of dread. But the general framing device is just so rote. Nothing was surprising; nothing was revelatory. It was a very pleasant picture book with a bit of surrealism and I did not come away from the experience re-examining myself.
