John Gregory Brown sets his novels in deepest New Orleans, where he grew up, writing in a style that the L.A. Times called “Faulkner Lite or a Percy au jus.” In Decorations in a Ruined Cemetery, Brown called attention to racial prejudice by withholding information (at first) on whether his central characters were white or black; in his new novel, The Wrecked, Blessed Body of Shelton Lafleur, he gives physical disability equally uncommon treatment, allowing the crippled title character to transcend his irreversible handicaps through art. Brown reads at 7 p.m. at Olsson’s, 1200 F St. NW. FREE. (202) 347-3686. (NodB)
