No Cowboys No Angels by Petie McCarty

Kellen Brand’s inheritance turns out to be a whopper–one dilapidated farm in West Virginia and one guardian angel!
Since Kellen is convinced no sane woman would choose to live in Riverside, she vows to sell her farm and quick. Her handsome neighbor Luke Kenyon must block the farm sale or risk exposure of his family’s secrets. While Kellen has located one potential buyer, she faces a town full of objectors. Someone is trying to frighten her off, and Luke is forced to step in and rescue her more than once.
Unfortunately, Kellen can’t seem to stay out of trouble. She stumbles onto a clandestine hazardous-waste-dumping operation next to her farm, and she prays Luke has one more rescue up his sleeve. It’s her only hope of staying alive.
Unless her mother really did leave her a guardian angel . .
