I'm a mother of a three-year-old, but when I started 'California,' my son wasn't even a twinkle in my eye. Because the book took as long as it did, I wrote it before I was pregnant, while I was pregnant, and as a new mother - so I enjoyed a diversity of experiences while creating this 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 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.

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.
