At age thirteen, he is mentally and developmentally between one and three years old and will need constant care for the rest of his life. Brown travels the globe, meeting with genetic scientists and neurologists as well as parents, to solve the questions Walker’s doctors can’t answer. In his journey, he offers an insightful critique of society’s assumptions about the disabled, and he discovers a connected community of families living with this illness. As Brown gradually lets go of his self-blame and hope for a cure, he learns to accept the Walker he loves, just as he is. Honest, intelligent, and deeply moving, The Boy in the Moon explores the value of a single human life.
