There seem to be this whole range of children's books be reprinted with adult covers or collector's edition with foil. I've seen Terry Pratchett, Hunger Games, Harry Potter, and many others. It seems to be a trend, but they all look the same, with a black background, little logo, and either foil or printed names. Almost as simple as the penguin orange band covers. If this look sells, why aren't there any indie editions using it?
