Good Resources for Parents and Others?

Hi all,

I'm a parent of a teenage boy who is probably somewhere on the spectrum of autism. There's a long wait for a diagnosis and we haven't managed to convince him that it would be useful to him yet in any case. However, I found a book that I found useful, and I thought others might too - or alternatively those of you who are on the spectrum might be able to say whether or not these resources are helpful / accurate to your experience.

The book I found is 'Autism and Your Teen' by Blythe Grossberg.

Has anyone else read it and have opinions on it? Or, other suggestions for good books?
