On opening day of the baseball season, 04/04/04, two well-known writers and serious Red Sox fans, Stewart O'Nan and Stephen King, began an intense e-mail exchange about their favorite team, which went on to do what seemed impossible—win the World Series. Just five weeks after that historic event, Scribner published the exchange. That book, Faithful, is the only new nonfiction hardcover to land on PW's charts this week. Total copies in print: 550,000.
