Maré Verde

Celina Rocha trades stolen calorie credits from a rusted ferry lashed to a drowned Recife tower, and she has never let conscience interfere with arithmetic. Then her mechanic fishes a girl out of a scuttled transport skiff—an indentured laborer with a perfect memory and an engineered algae genome locked inside her skull, the only thing that can feed three million starving people. A city-state enforcer wants it. A seed cartel wants it buried. And someone has hidden a weapon inside it.
