Simone has always felt different, though her life seems pretty normal. Her mom's a lawyer for the ACLU, so she's grown up spending her Saturdays outside the food co-op, gathering signatures for worthy causes. Her dad's a political cartoonist who does most of the work around the house. Her little brother is a jock who seems to know how to do everything just right. Her best friend has a new boyfriend, and Simone has a crush on a really smart and funny guy who spends all his time with another girl.But what really makes Simone different is that she doesn't resemble anyone in her family. She's adopted. She's always known it, and 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, life, the afterlife, and what it means to be a daughter.
