Andi Buckner and her twin brother, Bolden, have had enough of the rough streets of Detroit. When they can no longer bear the drugs and abuse within their home, the twins make their escape: Bolden to the military, and Andi to wherever the wind takes her. Andi eventually finds herself in Spring Hollow, Montana, taken in by a kind old man, Louis "Gramps" Granger, a retired cop. Andi soon finds a peace she has never known as she roots herself in the small town, working at the café and living in a cabin on Gramp's property. Her peace is short-lived, however, when an enemy from Gramp's past murders the old man. Andi's need to see justice served draws her into an investigation far beyond her own abilities, and after being reunited with her brother as well as with his friend, private investigator Mason Crowther, the trio delve into a mystery that goes far deeper than any of them imagined. With the truth almost within reach, they find themselves directly in the path of a killer who will stop at nothing to finish what they've started.
