Which of us might feel remotely interested in a book called The Burned Children of America? On the other hand, if it is called Zadie Smith Introduces the Burned Children of America, one is immediately intrigued. This collection follows the publication of the 81st Granta, the one that brought to us the best of young British novelists 2003, such as they are. Zadie Smith is the common factor linking these collections. In Granta, we read her short story ‘‘Martha, Martha’’, about a young British black woman, confused and homesick, looking for a cheap house in Boston. In the other volume, Smith introduces, as the cover blurb says, ‘‘nineteen of the best young writers from the USA’’. Smith has not edited this collection: one has to turn the pages and read closely to discover that its editors, Marco Cassini and Martina Testa, brought out the Italian edition in 2001. Smith, who herself made the transatlantic crossing only recently, makes a valiant effort to introduce us not only to these young writers, but also to America, and the inexplicable sadness of living there. Nevertheless, as she herself is rather a cheerful sort, her upbeat exhortations (‘‘Why so sad, people?’’ and ‘‘You can taste it in your morning Cheerios’’) only serve to heighten the gloom-tunes that lie within these pages. Fear of death and advertising, she offers, are the reasons for this terrible sadness. Advertising, does she mean — or the fear of advertising? We do not know, and we suspect it makes little difference. That part of Smith’s essay is rather weak, and filled with generalisations (‘‘Advertising doubles for life, supplants, creates simulacra’’). But within her breezy introduction (‘‘I was cringing my way through a reading’’) lie some astute observations about the writers included here.
