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. With few belongings and no specific destination, Andi eventually finds herself across the table from a kind old man in a quaint cafe in Spring Hollow, Montana. Louis "Gramps" Granger, a retired cop, takes Andi under his wing. Andi soon finds a peace she's never known as she roots herself in the small town, working at the cafe and living in a cabin on Gramps's property. But her peace is short-lived... When an enemy from Gramps's past murders the old man, Andi's need to see justice served draws her into an investigation far beyond her own abilities. But hundreds of miles away, her twin brother senses her despair and heeds her silent plea for help. Andi is soon reunited with her brother as well as with Bolden's friend, private investigator Mason Crowther. Together, the trio delves into a mystery and soon discovers that the murderer's motive 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...
