Judge a Book By Its Cover: Hardcover to Paperback

I haven't posted a cover change post in awhile, so I thought I would post some recent cover changes I've come across. I asked Mr. GreenBeanSexyMan as we were browsing the aisles of Barnes & Noble if it was sad that I could recognize a cover change when I see the book on the shelf, and he replied, "if you have to ask me if it's sad, it is." :) I'm so immersed in book covers all the time because of my job (how many times as a librarian do we have to find a book based on what the cover looked like?) that I recognize cover changes right away. Some I like and some I don't. I'm not the only one who notices these changes when browsing online or in bookstores, right?

What do you think of these:

Beneath a Meth Moon 

Hardcover:

Paperback:

-I really like how plain the hardcover is, but I think the paperback might have more appeal for teens looking for an obviously gritty read.

Mister Death's Blue-Eyed Girls

Hardcover:

Paperback:

-As creepy as the paperback is, it seems more juvenile to me. I like the mystery of hardcover.

Split

Hardcover:

 Paperback:

-This is another one where I really like both covers,  but there's something dark about the paperback that I find really appealing-I think it's the black and white photo with the red letters-it makes it stand out.

The Butterfly Clues

Hardcover:

Paperback:

-I really like the hardcover in this one-I think it's the color scheme in the hardcover I like better. But I really love how the butterfly inkblot more in the paperback.
