You should look into the now defunct line of horror, Dell Abyss. They have the covers you're looking for and a lot of them are very good reads. I would recommend any of their Kathe Koja books, Anthony Shriek, Wilding(or any Melanie Tem/Resnick-Tem book), Dead in the Water(its not great, but a decent read. good to read in the bathtub to give it that extra atmosphere of water), and Lost Futures.

I'd skip Harrowgate and Whipping Boy, unless you want something that doesn't take much effort to read before getting sleepy for bed.
