I usually have more than one thing I'm working on at once -- I've been working on three different novels. When I get stuck on one, I hop back and forth. It's sort of freeing: I can say I'm abandoning this thing that I hate forever and I'm moving on to something that's good. I'll find that I'll go back to [the other project] in a day or a week and like it again. But that moment of wanting to trash something -- that Virginia Woolf moment when you have to be stopped from filling your pocket with stones -- comes pretty regularly for me. Switching is probably a good thing.

It doesn't matter what you do. In the end, you are going to be judged, and all the times that you're not at your most dignified are the ones that will be recalled in all their vivid, heartbreaking detail. And then of course these things will be distorted and exaggerated and replayed over and over, until eventually they turn into the essence of you: your cartoon.

Writing short stories was kind of like I was cheating the whole time, in some way. I went back and forth between writing the novels and sort of sneaking out to work on stories occasionally. These stories were written over the last 10 years or so, as I was taking breaks from the novels I've written.

I've been reading Peter Straub since I was a teenager, and his work is hardwired into my brain. A Dark Matter contains echoes of all that has been great about Straub's previous work and builds upon it. This Rashomon-like tale is as spooky and frightening as anything he has written, but it's also an intense and moving celebration of love. Out of the darkness comes, ultimately, a surprising and haunting sense of joy.

Fiction is a particular kind of rhetoric, a way of thinking that I think can be useful in your life. It asks you to image the world through someone else's eyes, and it allows you to try to empathize with situations that you haven't actually experienced.

I guess I've been blessed with insomnia because I do a lot of my writing at night. Because I don't sleep as much as I probably should, I have that extra time to write weird stories and think odd thoughts.

I always worry that knowing too much about a novel or a story early on in writing will close it down - it feels fatalistic in some way.
