Query: Life saver

Within a few minutes of reading Karyn's book, I felt new hope for my son. If you believe that your child may be suffering from Autism, you OWE it to your child to read this book. If your pediatrician trys to discourage you, DO NOT LISTEN. If your friends or family attempt to discourage you, DO NOT LISTEN. This book can possibly save your child from a life of autism. It truly has been a life saver for my family.The book is extremely well written and despite the material, Karyn makes it enjoyable to read.
