I recently had a book out of the library (some of us actually still do this) which seemed quite interesting by the cover and the index. It was a man who hiked all over the place in this country and abroad. It turns out he was an academic on some sort of spiritual quest or pilgrimage, and I couldn't make head nor tail about what he was going on about. Even the few black and white pictures were odd - close up views of a couple of boulders and nothing to say where it was. It was so uninteresting I can't even remember the name or the author. Just goes to show that you can't always 'judge a book by its cover.'
