Susan Sontag (1933-2004) was one of America's first celebrity intellectuals. In the first biography to be published since her death, Daniel Schreiber portrays a glamorous woman full of contradictions and inner conflicts, whose life mirrored the cultural upheavals of her time.

While known primarily as a cultural critic and novelist, Sontag was also a filmmaker, stage director, and dramatist. It was her status as a pop icon that was unusual for an American intellectual: she was filmed by Andy Warhol and Woody Allen, photographed by Annie Leibovitz and Diane Arbus, and her likeness adorned advertisements for Absolut vodka. Drawing on newly available sources, including interviews with Nadine Gordimer, Robert Wilson, and Sontag's son, David Rieff, as well as on myriad interviews given by Sontag and her extensive correspondence with her friend and publisher Roger Straus, Schreiber explores the roles that Sontag played in influencing American public cultural and political conversations.
