Sebastian Junger

Junger, who in the past brought us works of brutal reportage such as The Perfect Storm, is on hand with a new book, War, in which he describes the life of American soldiers in Afghanistan—and dwells on the irrational things they must do while attempting to survive. He'll talk about the book with NBC's Brian Williams, who has covered the wars in Iraq and Afghanistan. A mixer ($12) follows at 9:15pm. See also Fri 14.
