With a laconic voice and a despairing sense of humor, film location scout Eve Broussard narrates award-winning Robison's (Why Did I Ever
) grim yet witty novella about the dissolution of a family and a city in the wake of Hurricane Katrina. Eve and unstable-but-armed Petal are married to 42-year-old twins, Adam and Saunders, who—not unlike the two black swans forever circling the statue commemorating their sister's suicide—spin their nearly identical lives aimlessly: drinking, fretting over hepatitis C and hording cocaine in their parents' stately New Orleans mansion. This family's Big Easy is a world where lush excess and harsh deprivation work side-by-side to create a malaise sinister in its paralyzing appeal. Told in terse, numbered passages, Robison's narrative is jumpy but effective, interspersed with and informed by startling statistics (“More than 50 former NOPD officers are in prison, 2 on death row”). Distilled episodes of mistaken identity, marriage trouble and potential infidelity build to a crucial decision for Eve, who may be damned if she does, damned if she doesn't. (Mar.)
