In the book world, things are always changing for better or worse.
One of those changes is the book covers. We usually see those changes made from the hardcover book to its paperback partner or even from the US cover to another countries cover. Sometimes those changes bring out the awesome-can-I-hang-this-on-my-wall to I'm-going-switzerland-on-this to the dreaded-what-the-bleeping-hell-were-they-thinking reactions in us.
I don't know about you but the book covers are always the first thing I look at, and sometimes I want the books just because of the cover. I want that awesome-ness on my shelf. I'd be lying if I said I haven't bought the same book just because the cover was different.

I had a hard time deciding which cover.
I like the PB for the colors, but the HC had more going for it.
