On such a full sea
(Book)

"In a future, long-declining America, society is strictly stratified by class. Long-abandoned urban neighborhoods have been repurposed as highwalled, self-contained labor colonies. And the members of the labor class--descendants of those brought over en masse many years earlier from environmentally ruined provincial China--find purpose and identity in their work to provide pristine produce and fish to the small, elite, satellite charter villages that ring the labor settlement. In this world lives Fan, a female fish-tank diver, who leaves her home in the B-Mor settlement (once known as Baltimore), when the man she loves mysteriously disappears. Fan's journey to find him takes her out of the safety of B-Mor, through the anarchic Open Counties, where crime is rampant with scant governmental oversight, and to a faraway charter village, in a quest that will soon become legend to those she left behind"--Provided by publisher.
