When park worker Laura Windstrom vanishes at Little Sahara State Park, her body is found staged beneath a blood-drawn spiral in the dunes. As more victims follow, FBI agent Laci Turner and local chief Bryce Barnes race to stop a killer who calls himself the Sand Walker. He knows the park, taunts the investigation, and turns the shifting sands into a ritual stage. With every murder, the circle tightens around the people hunting him. Dark, atmospheric, and relentless, this Oklahoma thriller blends psychological suspense, small-town fear, and a killer who wants to be remembered.
