THE FLOATING WORLD takes readers into the heart of Hurricane Katrina with the story of the Boisdorés, whose roots stretch back nearly to the foundation of New Orleans. Though the storm is fast approaching the Louisiana coast, Cora, the family’s fragile elder daughter, refuses to leave the city, forcing her parents, Joe Boisdoré, an artist descended from a freed slave who became one of the city’s preeminent furniture makers, and his white “Uptown” wife, Dr. Tess Eshleman, to evacuate without her, setting off a chain of events that leaves their marriage in shambles and Cora catatonic --- the victim or perpetrator of some violence mysterious even to herself.
