I don't know if this helps, but I had a similar problem getting through even one page in a good book. My mind would wander somewhere else mid page and when I realized it, I'd feel silly and have to rewind and rebuild context to continue reading. Usually felt a little ashamed to reread part of the page I had scanned the words of but didn't actually read with my thinking brain. Eventually what I realized was that these books were actually stimulating my thoughts at a higher frequency than the author intended. This is only really a bad thing if you need to get through the book under a certain deadline. Stimulating new thoughts is precisely why I read books in the first place! These days, when some sentence sends me on a mental rabbit trail and then consciously pause and follow it as far as I like before returning to the text. Overall this is a much more satisfying reading experience for me.
