Investigating a noise in the attic of her historic home, Maggie Holliday encounters a handsome man in a Civil War uniform. He calls her "Isabel", seduces her in ways the shy academic had never dreamed of, then literally vanishes. With every fleeting visit, Maggie's mysterious lover, Ethan, takes her closer to the edge of ecstasy and madness. Is he really a ghost? Far from chilling her, his touch is incendiary; it all feels so real and so very, very good. And so very familiar. Ethan insists Maggie's the reincarnation of his long-lost love. And after a few incredible nights in his arms, Maggie is inclined to believe him. But does she dare surrender to a passion that transcends time, tragedy, and even death?
