More than 100 fans enjoyed a lively conversation between bestselling authors David Baldacci (l.) and Kevin Powers at Story and Song Bookstore Bistro in San Fernandina Beach, Fla. Baldacci talked about growing up in Richmond, Va., in the turbulent '60s, where racism was prevalent, and how that influenced the writing of his new legal thriller, A Calamity of Souls (Grand Central). Powers's latest novel, A Line in the Sand (Back Bay), won't be released in paperback until May 21, so people scooped up signed copies of his previous book, The Yellow Birds,winner of the PEN/Hemingway Award.
