The book is the first-person account of a young African-American woman writer, Dana, who finds herself being shunted in time between her Los Angeles, California home in 1976 and a pre-Civil War Maryland plantation. There she meets her ancestors: a proud black freewoman and a white planter who has forced her into slavery and concubinage. As Dana's stays in the past become longer, the young woman becomes intimately entangled with the plantation community. She makes hard choices to survive slavery and to ensure her return to her own time.
