DAVID BIANCULLI, HOST:
I'm David Bianculli, editor of the website TV Worth Watching, sitting in for Terry Gross. Today's guest is Sister Helen Prejean, whose latest memoir, "River Of Fire," comes out in paperback this month.
You may know her and her story from her previous memoir, which was titled "Dead Man Walking." That book told how she became an activist against the death penalty. It was adapted into a film of the same name in 1995, starring Susan Sarandon.
