“Children don’t read ‘genres’; they read stories. Below a certain age, they don’t distinguish between ‘true’ and ‘not true,’ because they see no reason that a white rabbit shouldn’t possess a pocket watch, that whales shouldn’t talk, or that sentient beings shouldn’t live on other planets and travel in spaceships. Science-fiction tropes aren’t read as ‘science fiction’; they’re read as fiction. And fiction is read as reality. And sometimes reality lives under the bed and has very large teeth, and it’s no use pretending otherwise.”
