But what if you discover that the price of purpose is to render invisible so many other things?

We should feel an urgency about our environment and what's been done to it by human action and inaction. I wouldn't say there's a resurgence - I think it's been with us all along, and especially since the 1960s and 1970s, but it is true that there's almost a subsection of the bookstore devoted to it now. Personally, I've been addressing these issues in my long and short fiction since the late 1980s - basically since the beginning of my career.

I have received emails from readers who have said that they were emotionally impacted by the books, and they feel they are more environmentally aware and energized to do more. So that's hopeful to me. It is at least evidence of what I'm trying to do - trying to convey very intense emotional experiences by being very close in on character points of view to make you feel it in your body. That's one way to get the point across, by evoking a visceral response.

I see music as an aid. It overcomes my internal editor, especially when the music evokes the character or the mood I'm trying to build.

I’ve got...ways of tricking my brain into getting what I need out of it

I find myself in this bizarre position in which everything I write and talk about is pretty much about this issue, the environment. It feels a little too comfortable, because at the end of the day I can rationalize that I'm doing my share. I don't know if I actually am, I don't know if I should be more of an activist than I am. But at the end of the day, everybody needs to do those things that they're most likely to continue doing, and that aren't going to burn them out.

The map had been the first form of misdirection, for what is a map but a way of emphasizing some things and making other things invisible?
