I totally cheated for this post because ya know what? I went through my list of read books that were 2014 releases and a lot of the covers didn't IMHO deserve a Best Cover award. I'll admit to thinking the romance genre pretty much have the most boring covers ever. Oooh look another man-tittie woopedy-doo. *sigh* The Young Adult genre tends to really kick butt with gorgeous covers though.
Of these, I've only read the two but I have three of the others in either hardback or audio and the rest are on my wishlist. They're all books that first earned my interest thanks to beautiful cover art and then earned either a read/purchase/wishlisting thanks to their blurb.
You might notice a bit of a theme here. I like people on covers and in particular covers displaying motion whether it's hair blowing or the way a body is curved in movement. Did I pick one of your favorites?
