Scott Wallace – a veteran foreign correspondent - received a call one day in 2002 from an editor at National Geographic. Would he be interested in profiling a Brazilian explorer who was leading an expedition in search of the last uncontacted tribes in the world? Yes, he was. And within days Wallace left Manhattan to spend three harrowing months trekking into the heart of the Amazon jungle. The result is a new book called, “The Unconquered: In Search of the Amazon's Last Uncontacted Tribes.”
