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 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.

I am glad it's [California novel] resonated with people because, for me, most apocalyptic novels aren't scary, because they feel so very far off.

Oh my goodness, I hate camping. I am like Frida times 1,000. I have always been attracted to wilderness stories, à la the movie Badlands, when Sissy Spacek and Martin Sheen are in the woods on the lam - maybe because it scares me a little.

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 suppose that it's my impulse to mine, as a writer, these scary parts of ourselves and the world.

have a much harder time writing stories than novels. I need the expansiveness of a novel and the propulsive energy it provides. When I think about scene - and when I teach scene writing - I'm thinking about questions. What questions are raised by a scene? What questions are answered? What questions persist from scene to scene to scene?
