You can tell what really makes Simone different just by looking at her: she doesn't resemble anyone in her family. She's adopted. She's always known it, but she's never wanted to know anything about where she came from. She's happy with her family just as it is, thank you.
Then one day, Rivka calls, and Simone learns who her mother was—a 16-year-old, just like Simone. Who is Rivka? What does she want? Why is she calling now, after all these years? The answers lead Simone to deeper feelings of anguish and love than she has ever known and prompt her to question everything she has taken for granted about faith, the afterlife, and what it means to be a daughter.
