Don't judge a book by its cover - its an old saying but how important would you say the cover design is when it comes to sales? I just got my copy of an anthology I have a story in and, I have to say, I love the cover. Its a great follow on from the prior anthology and I think, objectively, it would draw my eye in a shop. (Subjectively I think every should buy a copy! no, two copies!) What do people think? Is the cover of a book important? Got any examples you want to share?
