The short story is so much about inevitability and this feeling that things always had to be this one way, and I wanted the apocalypses to blow that idea apart. I hope it feels that way. I hope the book invites people to read the stories in order and then, if they feel like it, maybe not read them in order the next time.

I'm a horrible historian. My memory is bad. I read things and then I forget them. I can't understand dates and I can't measure time. Time is confusing to me. That's why I do a lot of manipulations of time in my books, in part because an orderly time is physically difficult for me to conceive of in my brain.

The story, I like to say and remember, is always smarter than you—there will be patterns of theme, image, and idea that are much savvier and more complex than what you could come up with on your own. Find them with your marking pens as they emerge in your drafts. Become a student of your work in progress. Look for what your material is telling you about your material. Every aspect of a story has its own story.

For a really long time [before writing the novel], I was watching a lot of serial killer movies and I started to wonder if this was a trend and if other people were doing the same thing. That's what happens when you suddenly have a critical perspective on your own behavior.

I really like the interplay between thinking of text as ephemeral and thinking of it as a concrete, physical thing. With almost anything that I write, I'll stay completely immersed in the electronic text of it for a period of time and in another period, I'll stay immersed in it as a physical thing that can cut your skin. So with the apocalypses, I had them taped all over the wall and they had codes on them. Sometimes I would color code them in terms of thematic elements, sometimes in terms of voice, sometimes visual forms or images.

If you think it's worth writing a book about then that means you suspect that you're not the only one. You suspect that it has something to do with the larger patterns of your culture.

A lot of times when I ask people what their apocalyptic fantasy life is like, they'll immediately say something like, "Oh, what I think is going to kill us is climate change or World War IV," and that's not what I'm interested in at all. The point is not about winning a bet about what's going to happen. The point is about the human action of examining the possibility, the kind of obsessive imagining about it.
