Sheryl Sandberg's Lean In: reviews round-up Sheryl Sandberg, CEO of Facebook and previous Vice President at Google, has faced controversy over her first book. Lean In: Women, Work and the Will to Lead, deals with business leadership and how women can succeed in the workplace and is released in the UK on Wednesday. Sandberg, who earns a reported $30 million per year, encourages women to participate, or 'lean in' to get ahead professionally, and has received both criticism and praise for the controversial book. Here's what the first reviews have said: "Sandberg's advice to young women to be more ambitious, which can sound like a finger-wagging admonishment when taken out of context, is framed here in more encouraging terms - "What would you do if you weren't afraid?" - addressing the self-doubt that still holds many women back." Sandberg barely mentions the millions of single mothers in the workplace. She does, however, advise women on how to find a supportive spouse - who, in her book, is almost always male. Ambitious lesbians will have to find their tutorial elsewhere. Connie Schultz, the Washington Post "Sandberg's "sort of feminist manifesto," released on Monday, is at its best when it shines a light on sexism's shadowy, more hidden nooks.

Sandberg encourages women to take a seat at the table, raise their hands, and speak up, even as she recognizes that higher-ups often perceive women who do so to be running their mouths or interrupting men. But later, Sandberg mentions that she enlisted a career coach to train her to speak less. Amanda Hess, Slate.com
