Katherine Stewart is an investigative journalist who has written for Rolling Stone, The Nation, The New York Times, and the Guardian. She may be best known as the author of The Good News Club, about an organization bringing religious fundamentalism to elementary schools across the country.

We spoke with her about the evil genius behind the "4/14 Window," whether a "Better News Club" for children of atheist parents is a good idea, and how writing about religious fundamentalism is like going back to a bad boyfriend.
