From award-winning author Lori Armstrong comes a gripping tale of brutal murder, as former army sniper Mercy Gunderson learns anew when she returns to the family ranch that, for the weak, the western plains of South Dakota hold...NO MERCY.

The body of a teenage Indian boy found on land belonging to the Gunderson ranch is just the beginning. When a second teen is killed, the crime moves even closer to home for Mercy. The Iraq veteran is no stranger to death, but these murders are deeply personal, recalling all too clearly a childhood marred by violence and tragedy. The local sheriff seems strangely apathetic, so Mercy throws herself into an investigation that is driven by a desire for justice . . . and retribution. But as she digs up the truth behind the shocking crimes, she uncovers dark and dangerous secrets involving those she loves. Now she must race to stop a killer before everything she's fought for is destroyed forever.
