Try getting a book that you can both read. I still read to my kids at night and they love it. So, I will usually read a paragraph and then they will read a paragraph. It takes longer to finish the book but at least they are reading.
Another tip I can share is finding books he is interested in. Perhaps there's a book on a particular subject that he would enjoy, ie video games and how they're made, etc. How about magazines? As long as he is reading that's all that matters
Hope this helps
