Grace Winslow, the daughter of a mixed marriage between an English sea captain and an African princess, is swept up in a slave revolt after she escapes the family compound to avoid an odious betrothal. As the truth about the fortress of Zulina unfolds, Grace begins to grasp the brutality and ferocity of the family business—the capture and trade of slaves. Despite being held for ransom, viciously maimed by a runaway slave, and threatened with death, Grace sympathizes with the plight of the captives. She is especially moved by the African Cabeto’s passion, determination, and willingness to sacrifice anything, including his own life, for his people’s freedom. Leaning on the faith of her nanny Mama Muco, Grace risks everything to follow her heart.
