Hoping for a romantic honeymoon at an Arizona dude ranch, Marla and Dalton arrive to find a series of mishaps plaguing the resort. A nearby ghost town is suffering similar problems. Is it a coincidence that Dalton’s Uncle Raymond owns both properties? When the patriarch asks for their help in finding the culprit, Marla and Dalton jump on the trail. News of a local forest ranger’s death raises the stakes, especially when they learn the man was Raymond’s friend.

Since sleuthing comes more naturally to Marla than horseback riding, she throws herself into the investigation with her usual zest. But as she digs deeper, she discovers skeletons in the family closet. Someone means to drive Raymond out of business, and the reason may be linked to his past misdeeds. But Raymond isn’t the only one with secrets. The trail leads Marla from an environmental activist group to saguaro poachers to water rights proponents to an old copper mine beneath the ghost town. She’d better saddle up, rein in the clues, and find the killer before she becomes the next spirit inhabiting the haunted hillside.
