During the Civil War, the escaped slaves Dorcas and Caleb flee northward with the help of the Underground Railroad. But Dorcas has a secret gift that makes her very valuable to her incensed masters, who will stop at nothing to get her back--including killing those who would give her aid. Yet the seemingly simple farmers Elias and Jenny Sutherland have secrets of their own, secrets revealed when blood is shed upon the land.
