Christopher Boone has Asperger’s Syndrome and Haddon’s book is the best portrayal of what goes through the mind of a young teen who is simultaneously a brilliant mathematician and incapable of comprehending facial expressions, other people’s emotions, or jokes, to name just a few symptoms. The book follows Christopher’s attempts to write a mystery book about a murdered dog and does an astonishing job of describing what a wonderful kid he is and how unbelievably challenging it is to live with him.
