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.

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 was interested in writing about gender in this future world where progress has not only halted but turned backward. On another note, sometimes the personal is not so politically correct, and what we are turned on by can't be made to behave.

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 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 I knew what I was doing, writing an "apocalypse" novel, when I started this book. Now that the book is done, I can own that I have in fact written an apocalypse novel, one that speculates on a dark, dark future. Why I did it, I really don't know - every time people read my work they comment on its darkness, its sadness.

All crises, once averted, become jokes.
