Query: A 'must' for any serious health reference collection.

Usually books on Asperger's Syndrome address the diagnosis and options for children: The Complete Guide to Asperger's Syndrome broadens the field, using case studies and personal accounts from the author's own clinical experience to cover both adults and children, and all symptoms of the syndrome. From causes and diagnosis to differences in social interactions, perception, and mental health issues, The Complete Guide goes far beyond the usual Asperger's approach and is a 'must' for any serious health reference collection.
