Mark Seal has been a journalist for more than thirty years. Currently a contributing editor at Vanity Fair, he has written for many major magazines and served as a collaborator on almost twenty nonfiction books. Although he has written thousands of stories, Seal says none has struck a chord with readers more than the story of the incredible life and brutal death of Joan Root, which he originally reported in the August 2006 issue of Vanity Fair. He lives in Aspen, Colorado.
