In fourteen sweeping and sublime stories, five of which have been published in The New Yorker , the bestselling and Pulitzer Prize-winning author of The Known World shows that his grasp of the human condition is firmer than ever Returning to the city that inspired his first prizewinning book, Lost in the City , Jones has filled this new collection with people who call Washington, D.C., home.
