Thirty-six-year-old Grace McAllister never longed for children. But when she meets Victor Hansen, a handsome, charismatic divorced restaurateur who is father to Max and Ava, Grace decides that, for the right man, she could learn to be an excellent part-time stepmom. After all, the kids live with their mother, Kelli. How hard could it be? At thirteen, Ava Hansen is mature beyond her years. Since her parents' divorce, she has been taking care of her emotionally unstable mother and her little brother—she pays the bills, does the laundry, and never complains because she loves her mama more than anyone. And while her father's new girlfriend is nice enough, Ava still holds out hope that her parents will get back together and that they'll be a family again. But only days after Victor and Grace get engaged, Kelli dies suddenly under mysterious circumstances—and soon, Grace and Ava discover that there was much more to Kelli's life than either ever knew.
