Sandberg is the COO of Facebook and discusses how women (and society) sabotage women's careers. Women need to take risks, find partners who will assume their fair share of the household/childcare chores and 'lean in' to the challenges of the working world. I found Sandberg surprisingly self-deprecating and she mentions many of her mistakes and weaknesses. This book is very controversial (think Tiger Mom here) and has been featured quite a bit in the media. It's definitely a good conversation starter. Personally, many of her comments about how women are too focused on being pleasers or don't assert themselves really resonated with me and made me think of the many times where I did not 'sit at the table'. Very relevant for women in all positions.
