Shadow Sentinel

Shadow Sentinel: A Genetic Engineering Technothriller

Written by Rex Flint, the former Pentagon cyber operator who turns classified nightmares into edge-of-your-seat thrillers. Narrated by Juli Brooks, also a former Pentagon communications specialist and professional voice-actor who brings stories to life.

Monsters aren’t born. They’re engineered.

When a flash flood seals off Tall Pines, Georgia, ex–Air Force investigator Archer Lucas is dropped into a nightmare. Locals whisper about the Wampus Cat. The truth is uglier: A secret research lab has turned the Appalachian woods into a live test range for gene-spliced predators.

Cut off by rising water and dirty politics, Archer’s only reliable ally is A.L.I.C.E., an off-grid AI with her own secrets. By dawn, the bodies will stack up unless Archer can expose the operation, outmaneuver a federal smokescreen, and survive the hunt.

Shadow Sentinel blends Michael Crichton’s scientific dread with Stephen King’s knife-edge tension: biotech gone feral, a town under siege, and an investigator who refuses to look away.

You’ll love this if you’re into:

• Technothrillers like Jurassic Park • , The Terminal List • , Relentless • Survival horror like The Troop • and The RuinsDeep-state intrigue • , black-site biotech, and unstoppable monsters

Lock your doors. Keep the lights on. The hunt begins now.
