Quick summary: diverse women face diverse challenges. A book like this is obviously cathartic for these women, who talk (write) about their lives in a straighforward and honest manner. The beauty of this book is that none of the stories devolved into a "pity party," and none of these women came across as victims. They were stories of heroism, both in matters big and small, and accounts of women who showed courage, faith, and perseverance.
A lot of the women profiled in the book are "Facebook friends," so what I knew about them was what they posted on Facebook. The title is truly apt, as I learned what lies under the surface, beneath the layers, of so many amazing women.
