My ex-T recommended a book to me once: Thinking, Fast and Slow by Daniel Kahneman. I had actually heard of it before and thought it sounded interesting so I bought it, read it and didn't really like it because it was so slow etc. When I told my ex-T about it he said he thought it was slow too and that he didn't finish it for that reason. I wonder why he recommended it to me in the first place if he didn't really like it.
