History professor Georgia Bernard Hall and her daughter Violet are hurled back to 1859 by a mysterious invitation, an ancient oak, and a ritual that should never have touched them. Stranded on the eve of civil war, they're swept into the orbit of John Brown, Harriet Tubman, and Frederick Douglass; leaders fighting for freedom as whispers of old magic coil through the rebellion.
But the past is not only dangerous; it is haunted. Something ancient watches Violet from the shadows, drawn to her in ways she doesn't yet understand. As voodoo rites stir, as bloodlines awaken, and as long-lived beings move unseen through history, mother and daughter must navigate a world where destiny bends, power has a price, and the dead are not always gone.
To save each other and reshape a nation, they must confront forces both human and supernatural, discovering that the fight for freedom spans centuries, and some battles echo far beyond a single lifetime.
