RACHEL ZIMMERMAN, an award-winning journalist, is the author of Us, After: A Memoir of Love and Suicide. Her book examines domestic devastation and resurgence, the struggle between public and private selves, life’s shifting perspectives, the work of motherhood, and the secrets we keep. She will share how she confronted the unimaginable and discovered the good in what remains. When a state trooper appeared at Rachel Zimmerman’s door to report that her husband had jumped to his death off a nearby bridge, she fell to her knees, unable to fully absorb the news. How could the man she’d married, a devoted father and robotics professor at MIT with no history of mental illness, have committed such an act? How would she explain this to her young daughters? And could she have stopped him? A longtime journalist, she probed obsessively, believing answers would help her survive. She interviewed doctors and suicide researchers. She spoke with a man who jumped off the same bridge and lived. She got answers, but not the answer—the answer to the question of why her husband killed himself. And so began years of learning to make peace with not knowing.
