Nearly a century after “Dubliners,” with which James Joyce meant “to betray the soul of that hemiplegia or paralysis which many consider a city,” Roddy Doyle, who was born in Dublin in 1958, aims to evince, not just a paralyzed capital, but a paralyzed island, populated by 4 million and seemingly adrift in the tempestuous North Atlantic. The current immobilization results from strikingly different circumstances: Ireland’s precipitous and unprecedented economic growth, which has given it the second highest rate of per capita GDP in the European Union, and an immigration rate higher than the United States. “I went to bed in one country and woke up in a different one,” Mr. Doyle writes in a foreword to his new collection, “The Deportees and Other Stories” (Viking, 242 pages, $24.95).
