I think the book is going to be who you are. If you're a person of faith that will come out in the book. It's not something that you stick on or worry if you're clear enough. Because the minute you start doing that you've stopped telling a story and started writing propaganda. I think propaganda has gotten a bad name; it simply means you have something you believe that you want to share. But that's different from a story, where you don't start with an answer that you want to share: you start with a question that you need to explore. And you do that in the form of a story.
