Robert F. Kennedy, Jr. and Jenny McCarthy, discuss J.B. Handley's new book, "Underestimated: An Autism Miracle."

“Underestimated: An Autism Miracle” tells the remarkable story of Jamison’s journey to find a means of communication that allowed him to show the world that he was a brilliant, wise, generous, and complex individual who had been misunderstood and underestimated by everyone in his life.

Jamison’s emergence from his self-described “prison of silence” took place over a profoundly emotional and dramatic 12-month period that is retold from his father’s perspective.

Once Jamison’s extraordinary story has been told, Jamison takes over the narrative to share the story from his perspective, allowing the world to hear from someone who many had dismissed and cast aside as incapable.

Jamison’s remarkable transformation challenges the conventional wisdom surrounding autism, a disability impacting 1 in 36 Americans. Many scientists still consider non-speakers with autism — a full 40% of those on the autism spectrum — to be “mentally retarded.” Is it possible that the experts are wrong about several million people? Are all the non-speakers like Jamison?
