It'll set you back £9.09.
EDIT: You'll be able to pre-order the ebook version from around early November. That's standard practice. So no ebook pre-order button yet.
I also want to support the good old physical book shop. So I'll make an equal fuss when the book shows up in their catalogues, so you can go into your favourite establishment and order it there.
If you're in the USA, you'll have to wait a little longer. The hardback edition is released out there in April 2013.
As regular readers will know, London Falling is me once again chasing my central ambition: to make a success of being a novelist. It's (I hope) an intelligent supernatural thriller, about a team of modern undercover police who find they have to use real world police methods against something ancient and terrifying. If you liked my Doctor Who scripts (or particularly, I think, the Who novels), I think you'll find the same balance of danger and emotion.
At any rate, the day has arrived, and here we go! Please, please, spread the word! Thank you so much! And cheerio!
