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 organization 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. The author of The Corrections and Freedom has created yet another cast of vividly original characters, Californians and East Germans, good parents and bad parents, journalists and leakers, and he follows their intertwining paths through landscapes as contemporary as the omnipresent Internet and as ancient as the war between the sexes. Jonathan Franzen is a major author of our time, and Purity is his edgiest and most searching book yet
