Pip Tyler knows that her real name is Purity. But she doesn't have a clue who her father is, why her mother chose to live as a recluse with an invented name, or how she'll ever have a normal life. An encounter with a German peace activist leads Pip to an internship in South America with The Sunlight Project, an organization that traffics in all the secrets of the world. TSP is the brainchild of Andreas Wolf, who is drawn to Pip and the intensity of her response to him upends her conventional ideas of right and wrong.
