The thing I’m writing now, I have various characters, and all of a sudden, out of nowhere, this couple dies. And they have a daughter. …I thought, ‘OK, we have to do something with the daughter’ … then I realized she’s not really their daughter. She has her own story. And she’s become the most interesting character. She was this throwaway character that I didn’t even conceive of before I started writing her into it, and now she’s become very important in this book.
