Zoe Morgan was just ten years old when her sister, Rose, died of a rare illness, her parents turned into people she didn't know, and Zoe's lonely childhood drove her to excel in her studies. As a graduate of Yale, Zoe is temporarily working in a shelter for abused children in New York, where she meets child advocacy attorney, Austin Roberts. He is her first love and the man she marries. They have a perfect life and, with their daughter Jaime, Zoe knows that the aching void she has had for 24 years is finally gone. But it is only then that the true impact of Rose's death all those years ago affects their lives in a way that nobody could ever have imagined.
