Americans also carry small wounds, which they poultice incessantly but never seem to repair. These are the incisions of domestic insecurity and violence: the divorces, multiple marriages, single parents et al. Tobias Wolff wrote arguably the finest book that has ever attempted to come to terms with the small wounds. His memoir, This Boy's Life, captured the trauma of a young boy growing up with a violent stepfather in such vivid, unsentimental and light prose that it achieved instant cult status. Now Wolff is back attempting to deal with the larger wound.
