Charles Langley is the former news editor at the London Evening Standard, Europe's best-selling evening newspaper. Raised in England, he set out across the United States in 2003 to drive from Florida to California but wound up on a Navajo reservation in Arizona. At a peyote medicine ceremony he met a shaman named Blue Horse. After earning a degree in anthropology at the University of New Mexico in 2007, he became Blue Horse's apprentice and began compiling an archive on the workings of Navajo traditional medicine. He is the author of Spirit Land, the Peyote Diaries of Charles Langley. Langley and his wife, nuclear physicist Andrea Palounek, live in New Mexico.
