On a slab that’s all Katrina left of her Mississippi home, Tiger tells a story as American as Horatio Alger, Schwab’s Pharmacy, and a tent revival. She was a stripper, but is she now a performance artist and best-selling author? And is it really Barbara Walters she’s narrating this tale to? We’re too dazzled to know. Slab is how a girl ends up in the backwash of decadence and sin, and how out of the flotsam and jetsam she might construct a story of herself and the South to carry her to salvation.
