Stop the Press! New novel about Asperger syndrome! What an original idea!

I've just been taking a look at the Amazon page for Jodi Picoult's recent novel House Rules, which features a main character who has Asperger syndrome. I've noticed that some of the most unfavourable reviews of the book are from readers who claim to have Asperger syndrome themselves, and some of the most favourable reviews of the book are from readers who claim to be parents or related to people who have AS. No surprises there.
