In the 1680s the slave trade was still in its infancy. In the Americas, virulent religious and class division, prejudice and oppression were rife, providing the fertile soil in which slavery and race hatred were carefully planted and took root. A Mercy reveals what lies under the surface of slavery, and the opening chapter of the story of sugar, that great maw which was to eat up millions of lives. But at its heart, like Beloved, this is the ambivalent, disturbing story of a mother and a daughter in a violent ad-hoc world - a world where acts of mercy, like everything else, have unforeseen consequences.
