National Book Award winner Jonathan Kozol is best known for his 50 years of work among our nation’s poorest and most vulnerable children. Now, in the most personal book of his career, he tells the story of his father’s life and work as a nationally noted specialist in disorders of the brain and his astonishing ability, at the onset of Alzheimer’s disease, to explain the causes of his sickness and then to narrate, step-by-step, his slow descent into dementia.
