Camilla chews a fingernail and thinks. "The book in my room is in a language I can't read, so even if you read it to me I won't understand." Then she remembers: "This castle is magic. If you want something you only have to ask for it." Which makes perfect sense, for a dream castle.

She raises her little voice: "I want the Blue Fairy Book (http://etext.virginia.edu/toc/modeng/public/LanBlue.html). Please."

Sure enough, a house elf materialises with the book.

"There," says little Camilla, with a satisfied smile, and hands the book to her guardian/babysitter.
