Author! Author! The truth, in some of its most painful and messy permutations, still emerges triumphant in the works of Dorothy Allison and Bernard Cooper. Allison's portrait of poverty and abuse in America's rural South in her novel Bastard Out of Carolina gripped readers across the country, while her memoir, One or Two Things I Know for Sure, spun stories from Allison's own complicated family life. Cooper described a bit of his own personal hell in Truth Serum, a collection of autobiographic essays on family, AIDS, and growing up gay. Greg Riley interviews both about truth and memory within the creative process at 8 p.m. in the Herbst Theater, 401 Van Ness, S.F. Admission is $16; call 392-4400.
