Recently I've been seeing a number of covers that contain a translucent/shimmery/neon/ethereal/eye-catching image on a black background. I'm sure you know the kind of cover I'm talking about. While I'm not sure how well any of the following covers capture the essence of the story--being as I haven't read all of them--I think there's just something about them that will catch your eye in the store or library and make you want to read it!
How do you feel about these covers? Are you a fan of the black backgrounds, or if you're not, do you think they will attract attention and sell? Can you think of any other black background covers that you like?
