Centers on the extended visit of Helen Wentworth, a New England teacher, to a childhood friend's plantation, where she witnesses African slaves' arrivals and their sale and gross mistreatment at the hands of coffee and sugar planters. Juanita is a beautiful mulatta slave with whom the plantation owner's son falls in love. Extending the tradition of Gothic fiction in the Americas, Mann's novel raises questions about the relation of slavery in the Caribbean to that in the United States, and between romance and race, adding an important element to our understanding of nineteenth-century American literature.
