Karl Taro Greenfeld knew from an early age that his little brother, Noah, was not like other children. He was unable to communicate verbally or tie his shoes, and despite his angelic demeanor was prone to violent outbursts. No doctor, social worker, or specialist could pinpoint what was wrong with Noah beyond a general diagnosis: autism. The boys' parents dedicated their lives to caring for their younger son—a challenging, often painful experience that their father detailed in a bestselling trilogy of books.

Boy Alone is Karl Taro Greenfeld's unforgettable memoir of growing up in Noah's shadow, revealing the complex mix of rage, confusion, and love that defined the author's childhood—a beautiful, haunting, and wholly original exploration of what it means to be a family, a brother, a person.
