The first one was over 400 pages long… I read it to him in 3 days - anytime I asked him if he wanted me to keep reading or if he was ready for a break it was always, “keep reading!”
Often times he knew “secrets” in the book before they were revealed or before I even caught onto them… so I know his attention was captured.
Really enjoyable for the adult who is reading and for the kids who are listening.
Cheers.
