I hope I'm not posting this in the wrong place. It's my first time on here! Please forgive me if I am.
I read a book a long time ago and I'm wanting to read it again but I can't remember the title or author. Here's what I remember from it:
The cover of the book is a white/silver, long haired female vampire with her arms opened to you and she's kneeling and I think she has a dress on and I think it's short and maybe a little torn up. It's the end of the world or something like it, maybe wars are going on, I don't remember. I just remember there are fires and it's hard to find food and stuff. It's about vampires and I think they turn into wolves. A guy saves the girl and takes her to a cave or something. AHHH! It's so frustrating that I can't remember it.

I owned it and had it forever and I don't know what happened to it. I bought it for a quarter at the library when I was 13.
