Just when you thought they were gone, the novelists-from-the-eighties-who-the-critics-couldn’t-kill are back in force. First, we had Bret Easton Ellis’s Lunar Park, now the writer that Ellis fondly refers to as “The Jayster” is back, with “The Good Life.”Jay McInerney’s first novel in more than six years deals with ‘story of Luke, who is late for a breakfast meeting at the World Trade Center that Tuesday morning, as well as those of several characters first seen in Mr. McInerney’s 1992 novel, “Brightness Falls.”‘The entertainment quotient of McInerney’s novels seems to be inversely proportional to how “deep” they try to be. His first book, “Bright Lights, Big City” didn’t aspire to be The Great American novel, and, as a consequence, was extremely entertaining. By the time “Brightness Falls” arrived, McInerney was playing at being the voice of his generation, or at least that part of a generation who are famous novelists and date models. The gap between McInerney’s pretensions to universality and the narrow concerns of his own demographic more often generated bathos than pathos (Can anyone outside a narrow slice of New York City’s bourgeoisie actually stomach reading hundreds of pages on the marital travails of those coining it in the financial industries?)Given this dissonance, the prospect of the Jayster tackling the monument that is the memory of 911 does not inspire confidence.
