Wayward Angel — Patricia Rice

Fleeing to America to escape her wealthy and abusive father, a young woman is taken in and hidden by a Quaker family, but she is unable to keep her feelings for a local slaveholder's son secret when the Civil War breaks out

Her real name was Lady Alexandra Theodora Beaumont, the daughter of an abusive British lord. Rescued from near drowning by some kindly Kentucky Quakers, little "Dora" was disguised as a typical Quaker child and no one knew of her first years not even Pace Nicholls, "bad boy" son of a local slaveholder. And from the day they met, wherever Pace was, so was Dora, who grew to womanhood secretly pining for his love. Pace was a hellion as a boy and a rebel as a man. He freed the family slaves and left his law practice to join the Union army. And Dora was always there, ready to nurse his wounds. Pace had no excuse except war's insanity for taking her in a wanton self-indulgence and not giving his heart, never guessing that the tables would one day turn. He never guessed that the noble and beautiful Lady Alexandra who had once come so willingly into his arms, could be swept forever out of his reach unless this time he offered her his heart.
