Hidden Valley Road contains everything: scientific intrigue, meticulous reporting, startling revelations, and, most of all, a profound sense of humanity. It is that rare book that can be read again and again."-David Grann, author of Killers of the Flower MoonOne of the New York Times' "20 most anticipated books of 2020": the heartrending story of a mid-century American family with twelve children, six of them diagnosed with schizophrenia, that became science's great hope in the quest to understand the disease.
