Stone Cold Heart

When local rock climbers stumble upon abandoned human bones in a remote Texas gorge, Sara Lockhart is the first to get the call. She has a reputation as one of the nation's top forensic anthropologists, and police detective Nolan Hess knows she is just the expert he needs to help unravel this case. Although evidence is scarce, Nolan suspects the bones belong to a teenage climber who vanished last summer.

But as Sara unearths strange clues, she finds chilling similarities to a case from her past—a case that now threatens to rock Nolan's community. While Sara digs deep for answers, the stakes rise higher as another young woman disappears without a trace. Investigators work against the clock as Sara races to discover the truth, even if her harrowing search brings her face to face with a stone-cold killer.
