Angels Watching Over Me (Shenandoah Sisters Book #1) 

Book 1 of SHENANDOAH SISTERS. Two young Southern girls, one the daughter of a plantation owner and one the daughter of a slave, barely survive the onset of the Civil War and the loss of both their families. When these tragic circumstances bring them together, they join forces to discover if they can make a life for themselves. As their preconceptions give way to experience, they gradually learn to value their contrasting and complementing strengths and skills as they face the formidable task of keeping body and soul together in the aftermath of this devastating war. But is it possible the Lord they have come to know has something bigger in mind for the plantation than either of them can imagine?
