In his introduction to this one hundredth volume of the beloved  Best American Short Stories,  guest editor T. C. Boyle writes, “The Model T gave way to the Model A and to the Ferrari and the Prius . . . modernism to postmodernism and post-postmodernism. We advance. We progress. We move on. But we are part of a tradition.” Boyle’s choices of stories reflect a vibrant range of characters, from a numb wife who feels alive only in the presence of violence to a new widower coming to terms with his sudden freedom, from a missing child to a champion speedboat racer. These stories will grab hold and surprise, which according to Boyle is “what the best fiction offers, and there was no shortage of such in this year’s selections.” Mulling over the question of character likability, series editor Heidi Pitlor asks, “Did I like these characters? I very much liked reading their stories, as did T. C. Boyle.” Here are characters who “are living, breathing people who screw up terribly and want and need and think uneasy thoughts.”   T. C. BOYLE, guest editor, has published fifteen novels and ten collections of short stories.
