Confession time: I still haven't gotten around to reading Possession (it's on my to-read list! I swear!) but I've always loved, loved, loved its cover.
While I don't think it's better than POSSESSION's, SURRENDER's cover is still absolutely gorgeous, especially with that beautifully colored bird. I'm so happy they're continuing the trapped symbolism, first with the partially frozen butterfly and now the bird in the open jar.
The only thing I don't like that much is the shadowing at the bottom of the cover because it wasn't done in the first, but that's just a small nitpicky thing.
What do you think of SURRENDER's cover? Is it better than POSSESSION's?
