​Washington, March 22 (IANS) The first woman to serve on Facebook's board, who is now the Social media giants Chief Operating Officer, Sheryl Sandberg has announced the release of her latest book, which focusses on finding meaning and happiness after an adversity.

Titled "Option B: Facing Adversity, Building Resilience, and Finding Joy," the book has been co-written with author Adam Grant. 

In a Facebook post, Sandberg said that the book focuses on how she learned to find meaning and happiness after the sudden death of her husband, Dave Goldberg, in 2015. 

The title, Sandberg said, has been inspired by a conversation with a friend. 

"A few weeks after my husband Dave died, I was talking to my friend Phil Deutch about a father-son activity that Dave was not here to do. We came up with a plan for someone to fill in so my son would not have to miss out. I cried, 'But I want Dave.' Phil put his arm around me and said, 'Option A is not available. So let's just kick the shit out of Option B,'" Sandberg wrote in a post on Facebook. 

"That became my mantra, and for the past two years I've tried hard to find meaning and happiness in the wake of our despair." 

"Because no one's life is perfect, we all live some form of Option B," she wrote. "It's my deepest hope that Option B will help others learn what I learned: that when life pulls you under, you can kick against the bottom, break the surface, and breathe again."

Sandberg, who previously authored "Lean In" in 2012, she was named in the Time 100, an annual list of the 100 most influential people in the world according to Time magazine.
