Answer: ideas come from everywhere and anywhere. The first idea for The Volume of Possible Endings came from a fairy tale. It isn’t one of the best known ones, but I’d been interested by it since I was about ten or eleven. It’s a story of a girl who has either six, seven or twenty-one brothers depending on which version of the story it is. A wicked witch changes all the brothers into swans and the spell can only be broken if the girl sews shirts for them all. I remember thinking what a lot of work that would have been – especially if it was twenty-one brothers. She didn’t have a sewing machine, either. It all had to be done with a needle and thread. Yikes. What really grabbed my interest was how much she must have loved her brothers.
But of course, it would have been hard work for me as well to manage twenty-one brothers in a story. I decided that three brothers would be plenty for my story, thanks. And – this isn’t a spoiler – the brothers in this novel don’t get turned into swans. But there is magic involved, and magical wickedness.
Anyway, maybe there’s an idea here that you could use for writing one of your own stories. In fairy stories you never get a lot of information about how the characters feel. They just do things, or things just happen to them. So why not start thinking about why the characters in a fairy story come to do whatever it might be. How do they actually feel? Choose a fairy tale you especially like, say, Red Riding Hood. Why would a mother could send her precious child into a forest all by herself? Does Red Riding Hood really want to go into the forest? Or, think about how the wolf feels. For instance, how long is it since he had a good dinner? Or is he just a greedy-guts? Or a bully and a show-off? Could you tell the story from his point of view? That might be fun.
