Look Me In the Eye: My Life with Asperger's by John Elder Robison has been on my bookshelf and the 'next' book in my TBR for years.
John Elder Robison is the older brother of the more famous writer, Augusten Burroughs. He actually wrote this book at the urging of Burroughs and it - from reading reviews and such - is an amazing inside view to living a life with the disorder. Robison, it seems, didn't know that there was a name for his 'strangeness' until he was diagnosed in later life. It allowed him to find new ways to cope in social situations.
