“A generous gift—he invites us into places of wrenching, claustrophobic grief and the most intimate family joys. We come away feeling a little stronger, like we can somehow handle life a little better. . . . May well be the best thing published in 2022.”—Esquire

“[Delaney’s] writing had me drawn in from page one, and the book is written with gut-wrenching honesty. . . . I put this on a shelf with The Year of Magical Thinking, When Breath Becomes Air and Until I Say Goodbye. These books remind me to take time to experience every day with as much joy as I can.”—Book Reporter

“An intense, heartbreaking memoir about the illness and death of his toddler son. Will resonate deeply [with anyone] who's lost a loved one, especially a child.”—Margaret Atwood on Twitter

“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

“This book is so rich with grief and love and pain and humor and an incandescent, purifying, flame-throwing wrath.

At the heart of this intimate story of coming to terms with death is a stubborn embrace of life itself.”—Mat Johnson, author of Invisible Things and Pym

“I love this book, and it is a tough ride, filled with grace and beauty and unimaginable pain. I cried a number of times, laughed a lot, grieved with the Delaneys, and underlined so many moments of courage, exposure, humanity, and the deepest meaning. All I can say is, Wow.”—Anne Lamott

“This book is unlike anything I’ve ever read. Brutally honest, powerful, like a beautiful howl. A love letter to Delaney’s precious boy. To his wife. His family. To parenthood.
