A visceral and deeply personal memoir of loss, remembrance, and love.

In 2016, Rob Delaney’s beautiful, bright one-year-old son, Henry, was diagnosed with a brain tumor. The family had moved from Los Angeles to London with their two young boys when Rob’s wife was pregnant with Henry, their third. The move was an adventure and a challenge that would bind them even more tightly together as they navigated the novelty of London, the culture clashes, and the funhouse experience of Rob’s fame—thanks to his role as cocreator and star of the hit series Catastrophe. Henry’s illness was a cataclysm that changed everything about their lives. Amid the hospital routine, surgeries, and brutal treatments, they found a newfound community of nurses, aides, caregivers, and fellow parents contending with the unthinkable. Two years later, Henry died, and his family watched their world fall away to reveal the things that matter most.

A Heart That Works is Delaney’s intimate, unflinching, and fiercely funny exploration of what happened—from the harrowing illness to the bodily impact of grief and the blind, furious rage that followed, through to the forceful, unstoppable love that remains. Delaney grapples with the fragile miracle of life, the mysteries of death, and the question of purpose for those left behind. His memoir offers solace to those who have faced devastation and shows us how grace may appear even in the darkest times.

Rob Delaney is a comedian, actor, writer, and the author of a previous memoir, Rob Delaney: Mother Wife Sister Human Warrior Falcon Yardstick Turban Cabbage. He is widely known as the BAFTA-winning cocreator and costar of the critically acclaimed Amazon Prime comedy Catastrophe, which broadcasts in more than 130 countries. 

“As heartbreaking as the book may be, Delaney’s pitch-black humor buoys even the toughest moments…Delaney’s book is ultimately about all-encompassing, heart-exploding love.”

 —New York Times

“I could have read about Henry for a thousand pages. It is impossible not to share in Delaney’s tenderness, his attention, his anger, his night-black humor, and impossible not to see his son through his eyes: loved, learning, smiling ecstatically. I will turn to this book again and again, to feel deeply and to learn about this world from Henry.”

—Patricia Lockwood, author of No One Is Talking About This and Priestdaddy
