“Recent autism memoirs range from accounts of strenuous ‘healing’ to reflection on accepting the condition. Such a reaction isn’t found in Greenfeld’s book. . . . Karl resolves the conflict he sets up . . . with a surprise twist that may remind some readers of ‘The Sixth Sense.’” — Polly Morrice, New York Times Book Review

“Karl Taro Greenfeld grows from child to boy to man, variously resisting and succumbing to the force of his brother’s autism. The reader has no choice but to take the same emotional, heartwarming, tragic, comic, frustrating, loving, painful, uplifting journey.” — Paul A. Offit, author of Autism's False Prophets

“This is a truly beautiful and powerful book. Karl Greenfeld has written his own angle on the story of his autistic brother Noah, made famous in the works of their father Josh Greenfeld. Karl turns his sibling saga into a lyrical exploration of love, mystery, family, and what makes us human. He also dances around hope and reality, fact and fiction, in a way that will startle you. The result is a masterpiece of literature and memory that will leave you breathless.” — Walter Isaacson, author of Benjamin Franklin: An American Life

“A vivid, compelling, painfully honest sibling story. My heart went out to Karl. I couldn’t put this book down.” — Rachel Simon, author of Riding The Bus With My Sister

“A candid, brave, painful and very well-written memoir about a truly tragic family situation.” — Peter Matthiessen, author of The Shadow Country

“Sibling rivalry—and love—of a ravaging kind is the subject of this unsparing memoir of the author’s life with his severely autistic brother. [An] affecting chronicle of a family simultaneously shattered and bound tight by autism.” — Publishers Weekly

“Gripping.” — Suki Casanave, Washington Post

“Boy Alone unlocks the heart and lets the emotions pour out: grief, despair, anger, love, devotion and wonder. Whether you are a parent or a sibling of someone with autism or just looking in from the outside through this rarely opened window into the complex life of a family coping with autism, you will never forget this book.” — Portia Iversen, Co-Founder of Cure Autism Now and author of Strange Son

“Deep, dark, and devastating, Boy Alone is remarkable in its ruthless honesty, exceptional writing, and eye-opening subject matter. A fascinating and powerful read.” — Janice Erlbaum, author of Have You Found Her

“In his extraordinary memoir, Karl Greenfeld details what it is like to grow up next to a ‘beautiful’ boy with whom he can never play and never connect and who never returns his love, but who, nonetheless, is the most important fact of his life. Greenfeld’s story goes beyond autism, however; it is also a brilliant depiction of male adolescence and a meditation on what family means and what we owe one another in this life.” — Michael Thompson, Ph.D., co-author of Raising Cain
