"Oh it's terrifying, yeah: you come up to publication day and you suddenly realise 'right that's it, it's out in the world'. I remember when my publishers were telling me that it was starting to get on the bestseller list, and I was thinking 'Okay, well I've got a lot of family and a lot of friends, so okay that accounts for the first week'. And then I started realising that absolute strangers were gonna be reading it and...yeah it is quite terrifying actually."
