Murder the Mountains in Bloomington, MN

Wren and Rascal arrive at her third haunted campground writing assignment in the mountains of Tennessee and disturb the lair of a killer.
Wren and Rascal check in at the Tennessee campground that has no history of being haunted except for the ghostly sounds of stock car races at night.
As the feelings deepen between Wren and Justin, the town marshal who waits for her in Arizona, she's tempted to write a quick summary then leave Tennessee until she stumbles across a body.
While she pieces together fragments of old and new clues that reveal an ongoing crime, a ghost warns her of danger. The killer has her in his crosshairs.
