Cover Thursday: Silhouettes

Thursdays are dedicated to covers of upcoming releases or covers of books that are already on the shelves that I happen to love.
Let's talk about silhouettes, baby Let's talk about shadows and print. Let's talk about all the good things and the bad things that maybe. Let's talk about silhouettes.
....That was awful. *facepalm* But it really is all about silhouettes today since there comes a time when you get sick of looking at faces and dresses on covers. You still want to see people, you still want to see something, you just don't have to see all the details.
But these silhouette covers are not lacking details! Aren't they gorgeous?

 

What are you favorite silhouette covers?
