Goodreads asked Ruth Horowitz:

Where did you get the idea for your most recent book?

Ruth Horowitz I have a novel out on submission at the moment. The idea for it came from an entirely different book, which I never finished. In it, there was a scene in which a girl is walking through a park on her way home from school, and a girl she doesn't know is sitting on a park bench. This other girl is slightly older than the protagonist, and she's dressed outlandishly, and as the protagonist approaches, the girl on the bench says something mean to her. I got interested in who this other girl was...and the answer turned into its own novel.
