I loved John Urbancik's DarkWalker.This was a really cool, fun book that I had a hard time putting down. It's really a dark (or maybe urban) fantasy about a man who has the ability to see the creatures of the night--vampires, zombies, werewolves, etc.--and has some sort of supernatural protection from them, but he's only allowed to watch and can't interfere. This causes some trouble when he falls in love and has to rescue his lover from an imp, which turns his protection into a sort of psychic signal advertising him as an all you can eat buffet for monsters.
There's all kinds of other stuff. There are lots of monsters of all sorts. There's a sexy vampire, who kidnaps the hero and tries to help him because she falls in love with him. There's a tough as nails vampire hunter who helps the hero because it gives him a chance to kill monsters. There's even a demon with a sinister agenda.
I wouldn't call it the most original thing ever, since books about people who are aware of a secret world of monsters that coexists with our own are a dime a dozen these days. Still, if you're a big fan of horror or fantasy, you should check this book out.
