As a dad of eight, preparation for World Book Day starts early in my house. Unfortunately, the 'early' assertion usually relates to the morning of the day itself, with my wife and I rifling through the fancy dress box to match outfits to much-loved book characters for our children to wear. While lack of forethought is undoubtedly quite remiss on my part, I work in children's publishing, and so the annual event should have long since ceased to creep up and surprise me. I do love the whirlwind of chaos that results from trying to conceive plausible outfits that look like favourite book protagonists. In an instant, an oversized black coat becomes a wizard's cloak, and a smattering of face paint transforms a child wearing an orange t-shirt into the Cheshire cat.
