In 1790, Lavinia, a seven-year-old Irish orphan with no memory of her past, arrives on a tobacco plantation where she is put to work as an indentured servant with the kitchen house slaves. Though she becomes deeply bonded to her new family, Lavinia is also slowly accepted into the world of the big house, where the master is absent and the mistress battles opium addiction. As time passes she finds herself perilously straddling two very different worlds and when loyalties are brought into question, dangerous truths are laid bare and lives are at risk.
