==Book Description==
STAR IS RUNNING FROM THE PAST.
With her mama dead and no way to provide for herself, Star Campbell ran away from Luke's Saloon and straight into the arms of Michael Riley. Her life of degradation and discrimination over, she longs for a new better life. But Star has a secret past she cannot shake. Michael Riley is a simple farmer. Once burned badly by love, he's disinclined to fall for a beautiful woman. Michael's sense of chivalry compels him to take Star into his home, and she soon wins both his mother's and daughter's hearts. Before long, Michael finds that he can't seem to guard his own heart either, either. God forgives and forgets-but can man? When old hurts and prejudices resurface, can God teach Star and Michael to see other through the loving eyes of His grace?
