Books (Ellie and the Harp Maker)

Hi, I've just finished reading a book; 'Ellie and the Harpmaker,' It was a brilliant read and I would reccomend it to anyone who likes reading no matter what genre is your favourite. The reason I'm posting about it on here is because one of the characters in the book; Dan Hollis, i think could be on the Autism spectrum. It seems fairly obvious once you've read through the whole book. I was wondering if firstly anyone had read this book and thought the same, and secondly whether anyone knew of any fiction books that also had characters with autism but the book was not directly about the autism?

Thanks
