After her husband died suddenly from a cardiac arrhythmia, Facebook's COO Sheryl Sandberg (Lean In) thought she would never experience true joy again. Nearly two years later, she is out with a new book, Option B, that delves into how she proved herself wrong— and how others can build resilience in the face of trauma, too. Sandberg wrote Option B with her friend Adam Grant, an organizational psychologist and Wharton professor. They both join Katie onstage at 92Y (92Y.org) in Manhattan to discuss insights from the book, including how to support grieving children, dating after loss, and the "three P's" that can hinder recovery.
