Spooky, sexually explicit contemporary romance / supernatural / horror. Heroine is stalked by a psycho who is obsessed and I mean obsessed with her. He is killed in a car accident and comes back as this malevolent poltergeist - determine to possess her. The hero is a tortured soul (also dead) who is sent to protect her.
I've not read scary paranormal written by Couper before. At first I wasn't sure if I'd like it but then became so invested I couldn't put it down. I don't think this novel is for everyone but if the premise described appeals, you might like to give it a try.
