Appignanesi, Lisa. Simone de Beauvoir, London and New York: Penguin, 1988.
From the publisher:
Simone de Beauvoir was a member of the intellectual elite of philosopher-writers whose feminist ideas revolutionised conventional thinking. She is known primarily for her monumental work: The Second Sex, (1949) a scholarly and passionate seminal work, which became a classic of feminist literature but also for her partnership with the philosopher Jean-Paul Sartre, France’s most celebrated and unconventional intellectual couplings.
