This story of a slave's unrequited love for the woman who possessed him is set in 19th-century colonial Cuba. It is the only known feminist and abolitionist novel published during the 19th century in Spain or its colonies. Sab is a pioneer novel in that it is not merely concerned with improving the treatment of slaves or putting an end to the trade in Africa; it is an impassioned declaration of human rights. This new annotated critical edition provides the original Spanish text, an authoritative English introduction, maps and tables which relate to 19th-century Cuba, and a vocabulary list.
