Summary
Mom cries all the time. Dad acts strangely and nervous. Suddenly, 12-year-old Bethany Cole finds herself in the car with them, frantically driving across several states in the dead of night. With no explanation, they leave her at a house in Illinois with a woman Dad calls Aunt Myrlie. Myrlie is visibly shaken to see Dad, and she's even more stunned when she sees Bethany. "She looks just like . . ." she begins. Mom and Dad, upset and weeping, drive off into the night, leaving Bethany with a stranger and a hundred unanswered questions.
Later, Bethany hears Myrlie talking to Dad on the porch of Myrlie's house. Myrlie says he has to tell Bethany about Elizabeth. Bethany begins asking questions, and Dad, who vaguely indicates by phone that he's in danger, allows Myrlie to tell Bethany about the past. Bethany learns that Elizabeth was her parents' first daughter, a sister she never knew existed. Myrlie is her mom's sister, and the two families lived near one another when Elizabeth and Myrlie's daughter, Joss, was young. Elizabeth and Joss were cousins, best friends, and Olympic gymnastic hopefuls. But around the girls' 13th birthdays, the two families made a road trip in which an accident took the lives of Elizabeth and Myrlie's husband. Bethany's mom, who was driving, always blamed herself for the crash. After that, Bethany's parents left town. Myrlie hadn't seen or heard from them in years until the night they left Bethany with her. Bethany is also shocked to learn that her father, whom she always believed to be some kind of money manager, used to be a doctor.
Joss comes from St. Louis to stay with Myrlie and Bethany. They watch old videos, and Joss is struck by how much she looks like Elizabeth. They don't just resemble one another; it's as though they were twins. During her time with her aunt and cousin, she discovers many ways in which she is similar to her dead sister. She also becomes increasingly aware the life she's been living is a lie. Her father sends a package containing several birth certificates for Bethany, all with different last names and cities of birth. He also sends wads of $100 bills. Myrlie, Joss, and Bethany can only speculate what Bethany's dad might have done for that cash or what kind of trouble he's in. Mom calls during one of her delusional episodes, creating more questions.
