After writing two books that brought him little financial success, reporter Mark Bowden says he didn't expect life to change much when he wrote his third book, "Black Hawk Down". The book earned considerable praise from critics, was a finalist in the 1999 National Book Awards, and was made into a blockbuster movie that was released earlier this year. Bowden's most recent book analyzes a U.S. military campaign in another part of the world, this time in Colombia.Guest: Author Mark Bowden
