A good friend of mine has been for 3 years writing about her family's journey with her first-born son who has autism and is now 21.  She has finished her book and it's due to hit bookstores in September I believe.  It's titled A Regular Guy Growing up with Autism; A Family's Journey of Love and Acceptance.  

She has a website which I think I have mentioned to you before, but here it is.  Love to know what you think of it if you have time.
