In 2011, I did an internship in Seven Dials, a junction in London where seven roads come together. I'd given up on writing after multiple rejections for my first novel, and I was starting to consider a career in publishing instead, but Seven Dials gave me such a strong idea for a setting that I couldn't resist picking up my pen again.

I often look at places and kind of mentally convert them to fantasy versions of themselves.

People question what I thought of Oxford. Students used to talk about the 'Oxford bubble' because the place can make you feel cut off from the rest of the world. I would forget there were places like London that were not centred round libraries and essays.

My silver cord - the link between my body and my spirit - was extremely sensitive. It was what allowed me to sense dreamscapes at a distance. It could also snap me back into my skin.

Encourage children to write their own stories, and then don't rain on their parade. Don't say, 'That's not true.' Applaud flights of fantasy. Help with spelling and grammar, but stand up and cheer the use of imagination.

The cool thing about my show and me is that I'm a writer, and I'm a writer first if I don't have music.

I want to live with that sense with the music I make, with the art I make, with the way I love my kids, with the way I am a father and a husband and a friend and a follower of Christ, I want to live with reckless abandonment to the truth of the Gospel.

I'm excited to see Cassie's fans and how they react to the ending of 'Clockwork Princess!' I love hanging out with readers and seeing the energy readers bring to a room: seeing so many people united in imagination is going to be wonderful.
