I recently reread a book I hadn't planned to and it was fun anyway. I tried for months to get my husband to read The Warded Man by Peter Brett because I knew he'd love it, but he never did pick it up. Finally, on a long road trip, I started reading it aloud to him. By the end of the trip, we were more than half done, so he was hooked and we both finished it up on our own time.
I used to reread in this fashion all the time, reading to my parents as they drove to and fro, or while my mother (a seamstress) was working. My mother is also dyslexic and never did read much, so it made me happy whenever she really enjoyed the books.
Side note, when I was 14 or so, we got a Discworld audio book from the library. A bell would ring to signal the scene changes. When I started reading the Discworld books to my parents, I would say "Ding" at scene changes. Happy memories.
