What is the author's style in Nobody Nowhere: The Extraordinary Autobiography of an Autistic by Donna Williams?

The autobiographical book, "Nobody Nowhere" by Donna Williams, is written in the first-person narrative. No one other that the author could convey the pain and fear that she experienced throughout her life due to the debilitating condition known as autism. Although Williams does not provide a clinical nor medical analysis of the condition, she provides a personal description of autism that to many remains mysterious in nature and to others is unknown at best or vastly misunderstood at worst.
