Someone knows my name / Lawrence Hill.

Enhanced descriptions from Syndetics:

Abducted from Africa as a child and enslaved in South Carolina, Aminata Diallo thinks only of freedom--and of the knowledge she needs to get home. Sold to an indigo trader who recognizes her intelligence, Aminata is torn from her husband and child and thrown into the chaos of the Revolutionary War. In Manhattan, Aminata helps pen the Book of Negroes, a list of blacks rewarded for service to the king with safe passage to Nova Scotia. There Aminata finds a life of hardship and stinging prejudice. When the British abolitionists come looking for "adventurers" to create a new colony in Sierra Leone, Aminata assists in moving 1,200 Nova Scotians to Africa and aiding the abolitionist cause by revealing the realities of slavery to the British public. This captivating story of one woman's remarkable experience spans six decades and three continents and brings to life a crucial chapter in world history.
