Two sisters. One mystery. A family changed forever.At the turn of the twentieth century, sisters Emmy and Callie Bullock are living a privileged life when their well-ordered Alabama household gets turned upside down by the arrival of Lily McGee. Arrestingly beautiful, Lily quickly-and innocently-draws the wrong kind of attention.After Lily has a baby, Callie witnesses something she was never meant to see-or did she? Her memory is a haze, just an image in her mind of Emmy standing on a darkened riverbank and cradling Lily's baby girl. Only when the sisters are separated does the truth slowly come to light-including a revelation that will shape the rest of Callie's life.
