This is a highly contradictory idea, and I hate to say that half of you reading this will (probably) disagree with me. Here goes.
I am asking you to… JUDGE A BOOK BY ITS COVER. Ahhh!!! Oh no!!!! What is this world coming to! Now hold on a second, listen to me. I am not telling you that you should LIVE by this. At all. But I am willing to say that fifty percent of GOOD books that I’ve read (or more) have a decent cover. Here’s how I think about it: If the Author sincerely wants you to read his book, he/she will put a good cover on it. He/She will take the time to find a good artist who can do his/her job well, and if he/she picks a cool one that you really like, you may relate to him/her in some ways. Do you see what I mean? Now again, I’m not saying that all good art leads to a good story, it just happens often.
