Explaining diagnosis to son who doesn't like to share books


I'm looking for advice on how to explain my 7 year olds diagnosis to him, and also for my nearly 10 year old who is awaiting ADOS assessment.

I know there are lots of books available and I'd love some recommendations, but my younger son is very resistant to reading from books. He is a great reader for his age and can understand text when playing screen based games, but show him a book and he's just not interested (he regards all books as boring even if he is interested in the subject).

So as well as book recommendations I'm looking for websites, apps, videos etc that explore autism that would be appropriate for primary age children. 

Thank you
