On the jacket, Sally J Rogers, Ph D states, "...........Adults with AS and parents of children with AS will find it a veritable encyclopedia.............". I certainly agree with this statement, but would add some qualifying remarks. It is undoubtedly intended as a detailed text for scholars and specialists in Psychiatry and Psychology who are fully versed in scientific investigatory techniques, and lay readers including even many with good levels of general education, will find reading it a daunting task. However, dogged persistence may well be very rewarding. For those general readers who wish to gain some insight into what has become known as Asperger Syndrome, I would recommend that they first read less demanding texts in order to obtain some general grounding in the subject - such as 'Asperger's Syndrome' by Dr Tony Attwood.
