Inhalt: Young Pip Tyler doesn't know who she is. She knows that her real name is Purity, that she's saddled with $130,000 in student debt, that she's squatting with anarchists in Oakland, and that her relationship with her mother – her only family – is hazardous. But she doesn't have a clue who her father is, why her mother has always concealed her own real name, or how she can ever have a normal life. Enter the Germans. A glancing encounter with a German peace activist leads Pip to an internship in South America with The Sunlight Project, an organisation that traffics in all the secrets of the world – including, Pip hopes, the secret of her origins. TSP is the brainchild of Andreas Wolf, a charismatic provocateur who rose to fame in the chaos following the fall of the Berlin Wall. Now on the lam in Bolivia, Andreas is drawn to Pip for reasons she doesn't understand, and the intensity of her response to him upends her conventional ideas of right and wrong. Purity is a dark-hued comedy of youthful idealism, extreme fidelity, and murder.
