That book is the tale of a young boy, Christopher who suffers Dawn syndrome. I heard somebody talking about the story telled in this book is false as Asprenger syndrom doesn't produce such behaviour as the ones described in the book. But I think that's not the point. Mark Haddon gives us the portrayal of a "not normal" boy, of his ideas and links and connections he makes among them. The author writed the book as though it is written by Christopher. He tells about him discovering his courage by making a journey we would say incredibly easy, but wich is incredibly hard and scary for him.I definetly suggest this book to everyone.
