The messiness [in my books] is nothing like an Atwood novel. For me, the deeper subjects are secrets versus intimacy, and how both beget safety but also threaten it. And there is a lot for me about loss, too.

I tossed off a mention of the pirates early on. And they became integral to the backstory. Sometimes now I imagine them in the woods. They scare me. All men. Dirty and wearing red.

I am not sure how a novel changes the world. I think it alters a reader's perspective by asking him or her to see the world through another consciousness. That can perhaps cause people to see their own lives differently. Or just give a single day, a single moment, a slightly different sheen.

I think that sharpens the intention of a scene and clarifies a story's arc. Of course, I don't seek the questions until after I've written a scene - or maybe after I've daydreamed it.

It's a bit scary to see my book come true: the recent (if minor) LA earthquakes, Hurricane Sandy, the Boston bomber, and so on - much of it stoppable, I think, and yet I, too, am also guilty of passivity.

I did a lot of this through writing flashbacks. Many of the flashbacks took place at Cal's school and I eventually cut them because they didn't seem essential and they slowed the pace of the story in the first third of the book. They were essential to me, though, in that I learned about my characters.

With my students, I don't offer any simple tips like that, maybe because my own process is pretty messy, but when we workshop we talk a lot about the deeper subject, which is what the story or novel is about. I think defining a narrative's themes can lay bare a narrative's tensions.
