Born in 17th-century Ghana, half-sisters Effia and Esi might as well live worlds apart. One marries an Englishman–a slaver–and moves into his castle; the other is sold into slavery and kept in the dungeon beneath the very same castle. From there, Gyasi weaves a story that spans continents, generations, and three centuries of history as she explores the consequences of colonization and the legacy of slavery in both Africa and the United States. This unflinching and unforgettable novel is creatively imagined and completely transfixing, and it is one hell of a debut. Gyasi has made her mark as a writer to watch.
