The Ghost in My Brain: How a Concussion Stole My Life and How the New Science of Brain Plasticity Helped Me Get It Back is a nonfiction autobiographical story written by Clark Elliott. It's available as an eBook, audiobook, and those paper things your grandparents used to read.
Clark Elliott was the victim of an auto accident resulting in a concussion which severely limited his abilities. After dozens of doctors told him he'd just have to live with it, he found two that could repair much of the damage using a series of puzzles and special glasses.
Story. While I feel terrible for the author and all the challenges he had to deal with, his story was fascinating and had a happy ending.
Eye/Brain/Body Connection. I had no idea the eyes were connected to so many systems of the body, and that by altering the light that entered and adjusting where it focuses on the retina affects brain paths and emotions.
Repetition and Details of Difficulties. The author spends waaaaaay too much time describing his difficulties in waaaaaay too much detail. I actually skipped past a few chapters.
