A decorated soldier comes home from Afghanistan to bury his best friend -- and walks straight into a murder no one believes is real. Sergeant First Class Sherman Masterson served beside Josh Saunders in some of the most dangerous corners of the world. But it's the quiet farmland of Parmigan, Oklahoma, that delivers the blow he never saw coming: Josh is dead, and the official cause of death reads "natural causes." His father isn't buying it. When Walter Saunders gathers his son's three closest Army friends in a small-town diner and insists Josh was murdered, Sherman can't walk away. What starts as one grieving father's suspicion unravels into something far larger -- a trail of toxic exposure, corporate secrets, and a chain of violence that stretches from a rural Oklahoma farmhouse to mining operations on three continents. As Sherman, Major Aleesa Martin, and Michael Thurman dig deeper, they discover that someone with enormous resources wants this death to stay buried. The closer they get to the truth, the more it becomes clear: surviving Afghanistan may have been the easy part. A gripping thriller of friendship, loyalty, and a conspiracy that reaches further than anyone could imagine. Are you ready to find out what really killed Josh Saunders?
