David Nicholls: 'I'm desperate that the next book shouldn't disappoint people' - Features - Books - The Independent

It's death to think about a perceived demographic when you write a novel. With One Day, I just wrote the book that I wanted to write; I didn't think "I might have to expand on this section to appeal to men" or anything like that. I was anxious that it might only make sense to people aged between 38 and 44, who lived in London and had been to university or had certain political and cultural experiences. Thankfully that turned out not to be the case.
