Sheryl Sandberg--Facebook COO, ranked eighth on Fortune's list of the 50 Most Powerful Women in Business--has become one of America's most galvanizing leaders, and an icon for millions of women juggling work and family. In her Lean In , she urges women to take risks and seek new challenges, to find work that they love, and to remain passionately engaged with it at the highest levels throughout their lives. Lean In--Sheryl Sandberg's provocative, inspiring book about women and power--grew out of an electrifying TED talk Sandberg gave in 2010, in which she expressed her concern that progress for women in achieving major leadership positions had stalled. The talk became a phenomenon and has since been viewed nearly two million times. In Lean In, she fuses humorous personal anecdotes, singular lessons on confidence and leadership, and practical advice for women based on research, data, her own experiences, and the experiences of other women of all ages. Sandberg has an uncanny gift for cutting through layers of ambiguity that surround working women, and in Lean Inshe grapples, piercingly, with the great questions of modern life. Her message to women is overwhelmingly positive. She is a trailblazing model for the ideas she so passionately espouses, and she's on the pulse of a topic that has never been more relevant.
