This is what we came up with. Sorry it's only the hair – I’m still loath to put pictures of my children on here.
I have to admit that I almost didn’t put Zoe into The Dragon Box. After all, I was writing the book for boys. I’m glad I did though. I’m glad I made her tough. But maybe it’s also good that I didn’t describe her too well. Sausage, at least, had the chance to picture her for herself.
I've never particularly liked books that have people on the cover. I always like to imagine what a character looks like and it rarely matches what the cover designer has used; and though my own main characters tend to be based on well-known people, I would never tell anyone who I had in mind. It’s part of the pleasure of reading, to imagine those things. The fact that I imagined Alan Rickman as Severus Snape long before the movie came out was a bonus, though JK Rowling says she wasn’t describing him. It was fun to see how Sausage saw someone out of my head!
