In May 1653, young Frederica (Freddy) O'Brennan and her sister Aileen trust a stranger on an empty beach in western Ireland, inadvertently placing themselves in the crosshairs of Cromwell's notorious Reign of Terror. Freddy awakens in the crammed hold of a slave ship bound for Barbados. She and Aileen endure the gruesome voyage only to be wrenched apart when purchased at auction by sugar plantation owners from different islands. Freddy is left alone to face the brutal realities of life as a female Irish slave on a seventeenth century Barbados plantation. As she struggles to survive the ordeal, Freddy's harrowing experiences paint an intimate, compelling portrait of 1650s Irish and African slavery in the Caribbean.
