I can say without reservation that these stories are (almost without exception) marvelous. Funny and allegorical, they are a lot like bones: let them simmer slowly over a steady heat and they give up riches. Yet my students, who I thought would be sucked in by the fantastic elements and young adult protagonists, were put off and confused by them. They asked things like “Do the goggles really let them see ghosts?” and “Are the girls werewolves?”—which is fine but only if you’re willing to accept that the answer is “Yes. But maybe not.” And then to think about how “yes” changes your sense of the story, and then how “no” and “maybe” do. For reasons I don’t really understand, my class wouldn’t go there and got hung up on the ambiguity generated by the conceits.
Here’s my dream though: they have read the thing and someday, they are going to be at a cocktail party, trying their best to fit in and to impress but failing and when they leave and become self-hating and say to themselves (or to their significant other) something along the lines of “I’m like an animal and am not fit to attend these things and I don’t understand why anyone would invite me to wander loose among the humans like that,” they’ll remember this book and think “oh, wait, I get it now…”
