As Twilight Falls by Amanda Ashley

Kadie Andrews is traveling across the West to photograph ghost towns when she takes a wrong turn. She ends up in Morgan Creek, Wyoming, a spot that isn’t on the map. It’s a quaint little place, but there’s something strange and sinister about it. No cell phone reception, no gas for her car, no hotel. She can just move into a vacant furnished house. No one pays for anything. And no one can leave once they come to town.
Unable to find any way out, Kadie is a prisoner hunted for her blood, in a town full of vampires and their human prey.
