Writing a book and need feedback please?!?

I'm currently writing two potential novels and I'm hoping to get some feedback on the premise of one of them. I'm about 10,000 words in but this is the premise: In a different world much like our own a girl finds herself possessed by a demon after she is murdered by one and doesn't die. If she wants to have any life away from her demon she must go to Hell itself and reclaim her soul; but she won't get there if her killer has anything to say about it..........so that's the really rough and just thought up premise of it. What I'm asking is if you saw this book on a shelf would you read it?
