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.

For me, even when I was pregnant, I wondered, Should we even have children if we're bringing them into this horrible, scary world? But I did have a child, despite these fears - or because of them - and these fears are both contemporary and as old as time.

California seemed to me to be all about secrets and the need for safety. And this leads to this thematic messiness I'm still trying to figure out what to do with. I mean, when it comes to the themes, this is nothing like an Atwood novel.

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.

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

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 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.
