On a Stormy Night, a Restless Spirit Asked Me to Pass on a Message

Aaaah! Why Do You Keep Giving Me These Messy, Ambiguous Romance Stories?! Why?!

I want to read books similar to "The Last Bus on Route 13". I don't mind what the protagonist is like, but no romantic ambiguity! There can be a couple, but no will-they-won't-they tension, or keep it to the extras. It also needs to be compelling enough to keep me reading. If it's a power fantasy, it still needs to make sense, not be mindless. The suspense and fantasy elements should be tightly paced.
