I tried half of a “Head First” which claims to addressing this problem with cognitive science methods (eccentric pictures, repetition, handwriting, and dialogue style). At first it feels good, but after half of the book, I realized all of these can be done in my head even when reading non-head-first books. An engaged reader will do more than just “reading”, but actively comparing the content with own experience, trying to prove or disprove the argument, and sometimes making up stories to help them to memorize the content. So I would argue it's not books that aren't working, but a certain way of reading that's not working. Books with these techniques externalize part of the engaged reading process, but it may not be the optimal way for a specific person. For the books that a person themselves can actively engaged in their own way, these techniques can be noisy and redundant. For those they wouldn't have been actively engaged (like the leisure reading mentioned in the post), these techniques could be useful. But the person doesn't expect to get that much out of the books in the first place.
