The Hidden Bones (Evelyn Mercer)

A disgraced archaeologist.
A canyon that shouldn't exist.
A truth buried deeper than stone.

After a career-ending disaster in Cairo, Dr. Evelyn Mercer has sworn never to set foot on another expedition. But when a mysterious stranger delivers a field journal tied to her family's past, she is drawn into the remote Havasupai wilderness-and into a canyon that swallows compasses, erases echoes, and refuses to let its dead rest.

What begins as reluctant curiosity becomes a descent into a world carved by ancient hands. Following a trail hidden for generations, Evelyn uncovers forbidden chambers, impossible murals, and skeletal remains that challenge everything archaeology believes about human history. The deeper she goes, the clearer it becomes: someone died to keep these secrets buried... and someone is still watching.

To survive, Evelyn must confront not only the truth beneath the canyon, but the truth within herself-about legacy, loyalty, and the cost of rediscovering who she was always meant to be.

Some secrets are lost.
Others are protected.
And some were never meant to be found.

Randy R. Gillespie is the author of the HELIX series, a grounded biomedical thriller exploring the collision of science, military power, and human consequence. His work blends cinematic pacing with deeply researched medical and technological realism, focusing on characters forced to confront ethical collapse in moments where survival and morality can no longer coexist.

Drawing from a fascination with systems-how they're built, weaponized, and ultimately fail-Gillespie's storytelling avoids supernatural shortcuts in favor of plausible science pushed just beyond its breaking point. His narratives emphasize psychological realism, moral accountability, and the terrifying momentum of ideas once control is lost.
