Susan Sontag was our last great literary star. Her brilliant, serious mind combined with her striking image, her rigorous intellectualism and her groundbreaking inquiries into what was then seen as 'low culture' - celebrity, photographs, camp - propelled her into her own unique, inimitable category and made her famous the world over, emblematic of twentieth-century New York literary glamour. Today we need her ideas more than ever. Her writing on art and politics, feminism and homosexuality, celebrity and style, medicine and drugs, radicalism, Fascism, Freudianism, Communism and Americanism, forms an indispensable guide to our modern world. Sontag was present at many of the most crucial events of the twentieth century: when the Cuban Revolution began, and when the Berlin Wall came down, in Vietnam under American bombardment, in wartime Israel and in besieged Sarajevo. Sontag tells these stories and examines her work, as well as exploring the woman behind Sontag's formidable public face: the broken relationships, the struggles with her sexuality, her agonizing construction of herself and her public myth. Sontag is the first biography based on exclusive access to her restricted personal archives and on hundreds of interviews conducted with many people around the world who spoke freely for the first time about Susan Sontag, including Annie Leibovitz. It is a definitive portrait of an endlessly complex, dazzling woman; one of the twentieth century's greatest thinkers, who lived one of its most fascinating lives.
