Please quit redesigning the covers of your books.
I've recently noticed that all of you are doing it. Instead of paying writers to write new books, I suspect you're just slapping new covers on whatever you've got and trying to trick us into buying it again and forgetting we've read it, or being too lazy to return it.
I could understand if it was a 20 year old book with a clearly outdated cover, but that's not the case from some that I've seen.
My trip to the book store was confusing instead of relaxing because of your wily ways, and I'm not even 100% certain I haven't read the book I ended up getting. Either that or I've just learned so much about Marie Antoinette that it is all starting to look similar, which I admit is a possibility.
But still, you're doing it with other books and it has got to stop.
