In this memoir of loss, acclaimed writer and comedian Rob Delaney grapples with the fragile miracle of life, the mysteries of death, and the question of purpose for those left behind.

When you're a parent and your child gets hurt or sick, you not only try to help them get better but you also labour under the general belief that you can help them get better. That's not always the case though. Sometimes the nurses and the doctors can't fix what's wrong. Sometimes children die.

Rob Delaney's beautiful, bright, gloriously alive son Henry died. He was one when he was diagnosed with a brain tumour. An experience beyond comprehension, but an experience Rob must share. Why does he feel compelled to talk about it, to write about it, to make people feel something like what he feels when he knows it will hurt them? Because, despite Henry's death, Rob still loves people. For that reason, he wants them to understand.

A Heart That Works is an intimate, unflinching and fiercely funny exploration of loss - from the harrowing illness to the vivid, bodily impact of grief and the blind, furious rage that follows, through to the forceful, unstoppable love that remains.

This is the story of what happens when you lose a child, and everything you discover about life in the process.

"Delaney is a phenomenal storyteller . . . A Heart That Works is in the same league as The Year of Magical Thinking in its stark, clarified articulation of grief" - Buzzfeed

"Tender, perceptive and strangely, darkly funny amid unconscionable tragedy... This is a rallying call against the polite timidity that we often show grief" - The i

"A viscerally extraordinary book" - How To Fail

"Vital and very, very funny... As much as I wish he hadn't had to write it, I am glad he did. Because such deaths do happen. And they largely happen in private... That he is able to do so with such guiltless, funny and disarming honesty is testament to the profound effect of Henry's short but meaningful life" - Guardian

"Like Catastrophe, which laughs at and celebrates the messiness of married life, A Heart That Works is tragicomic, a jumble of joy and fear and laughter and pain... bleakly fun" - Observer Magazine

"A devastatingly candid account of a parent's grief that will have readers laughing and crying in equal measure... Few would attempt to bring humor and levity to such an unbearably sad story, but Delaney manages to do so with grace, sincerity, and warmth" - Kirkus Starred Review

"The book is remarkable for how deeply it delves into the granular aspects of death... This memoir is a big-hearted depiction of personal pain, urging readers to appreciate what they have" - Sunday Independent

"The most moving, thought-provoking and intimate account of navigating grief that you're likely to read... Delaney's book is shot through with profound anger, flashes of humour and most of all the enormous, all-encompassing love he feels for Henry and his family" - Daily Express

"How do you go on when the very worst happens? That's the question Catastrophe star and comedian Delaney grapples with in this raw account of losing his two-and-a-half-year-old son Henry to brain cancer in 2018. There are moments of dark humour amid the heartbreak, but expect to start crying on page 17" - Grazia

"Wrenching . . . A Heart That Works is heartbreaking (and how can it not be?), but it's also an affecting portrait of a father's love for his son" - Time

"A heart-breaking, consoling, funny and angry lament . . . life-changing" - Irish Times

"[Delaney's] meditations on loss, family and hope are so profound you'll come out the other side of this book a different person" - i news, Best Books of 2022

"A raw, painful and, at times, darkly funny memoir . . . 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

"The pain comes less from horrifying details than from the way Delaney lures us into contact with the very aspects of our lives that are easiest to ignore: our fragilities, our constant proximity to calamity, our powerlessness to control what life brings, or when" - New Yorker

"A wrenching, unflinching and somehow often funny memoir" - USA Today

"It is a relief to read an account of grief that is not a series of hard-won life lessons wrapped in a gratitude journal . . . The result is a book that sings with life . . . That a book about a dead child is at times laugh-out-loud funny is a testament to Delaney's skill; in the hands of a lesser writer, the humor could seem dismissive or grasping instead of the natural release valve of a person who is highly attuned to the absurdity of the awful" - Washington Post

"A book that'll break a heart, and put it back together again...A life changing read" - Stylist

"Achingly beautiful" - People

"Extraordinary . . . it brims with chaotic life" - Sunday Times

"It is laugh out loud funny, and cry out loud sad, and warm as a huge log fire in winter and I could have carried on reading it for 1000 pages." - Mark Haddon
