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 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.

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.

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 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.

The issue is that my book, and so many others, are not available for pre-order from Amazon. I hadn't realized how much that mattered for new authors. And how much Amazon is hurting us.
