I'm picky I know, but it's the result of years spent reading novels that I found disappointing or time wasting. The common phrase 'don't judge a book by its cover' is very hard to follow and really not true. I use the cover as a point of reference all the time. I often flick back to it to double check what a character or setting looks like and I often find it hard to read a novel with an unappealing cover.
