Unlocked

Some of these covers were featured on the Bookends blog, but I'm going to add some more to the key covers copy catting:
Green by Laura Peyton Roberts



Suite Scarlett (and for that matter, Scarlett Fever) by Maureen Johnson


The Fetch by Laura Whitcomb


Incarceron by Catherine Fisher


Split by Swati Avasthi


From what I've read of the descriptions (because of these, I've only read Suite Scarlett), I think that Split's cover is most content-fitting. I love the old looking keys, but the novelty wears off when you see it so often.

Do you think any of them did it better or is more interesting? I'm not committed to loving or disliking any of them. They just don't stand out as memorable to me except for the fact that there are so many other covers with similar looks.
