Tomorrow morning, I'm getting on a train that will take me through a tunnel from my home land back to my home in London, and even though I am a digital reading designer and could download the file right this instant, only once I get off the train in twelve hours, I'll buy a brand new JKR book at the WHSmith in King's Cross/St Pancras, and I'll walk past Platform 9 3/4 on my way to the tube and give it a wink, just because, and all the way down to south of the Thames, I will stroke the spine, and smell the pages, and scan the blurbs and look at the choice of typeface and I'll drop my suitcase at my flat in Brixton, where I now live – twelve years after the first four Potter Books first planted the idea of London into my teenaged head and a drawing pencil into my hand – and then head to my favourite coffee shop and read all day and probably a bit into the night until I've finished it and, chances are everything will be pretty damn fine in Dorkania.

And no, it won't be HP, and yes, it will fell a bit off and likely break my heart in a very profound way just one tiny bit, regardless of whether I'll love or hate The Casual Vacancy, which in turn means I'll probably love it in that earnest, irritating way only the book nerds and escapists, Peter Pans and paper sniffers of the world ever have loved anything. The way only those who wink at Platform 9 3/4 ever will.

And that will be fine.

I'll see you lot on the other side. Be good grown ups and most of all: Don't let the muggles get you down.
