I start with an image, then I go from the image toward exploring the situation. Then I write a scene, and from the scene I find the character, from the character I find the larger plot. It's like deductive reasoning - I start with the smaller stuff and work backward.

I keep a daily journal of whatever weird thought comes into my mind, like when I had a dream I was in North Dakota in the middle of a blizzard and for some reason the Egyptian pyramids were there, too - that I was able to shuffle into the book.

Writing about women's sexuality is very scary for me because I'm always afraid I'll get it wrong.

I was worried that, as a college teacher, if I wrote too much about intergenerational sex my students would be creeped out.

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.

I think at a certain point the book develops a certain weight, or pressure. You've been pushing the rock up the hill for a long time and then it starts to roll and things do start to come together in the last two thirds.

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.
