I'm re-reading Philip Pullman's The Shadow in the North: my ninth grade is going to read it this semester. (Patrick complained that last semester's book, Emily of New Moon, had no plot. You want plot?! I'll give you plot!!) (Gratifyingly, most of his classmates liked Emily of New Moon, and not just the girls.)

I noticed on the copyright page that The Shadow in the North had originally been published in 1986 under the title The Shadow in the Plate. "In the plate"? What's that?! Then I realized he must mean "photographic plate": Sally's comrades run a photographer's studio. A shadowy evil in the north, photography... these are the leit motifs of Northern Lights (aka The Golden Compass). Where do they come from?

Photography (not to mention electricity) as a link to the spirit world was the object of much study in the nineteenth century — and Northern Lights is set in the nineteenth century, albeit a fantasy of the nineteenth century — no less than the Sally Lockhart quartet. The northern evil must come (via Milton) from Canaanite mythology, where the great Adversary had his seat in the north. God, anti-god, Pullman's atheism...
