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 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 biotech gone feral, a town under siege, and an investigator who refuses to look away.

I really appreciated the real-world knowledge Rex Flint wove into this story. Blending that authenticity with elements of folklore and cutting-edge technology makes for a gripping, well-rounded thriller.
The main character, a former soldier discharged for standing up for what’s right, is pulled back into action with a covert agency that feels like a modern-day A-Team. Each teammate brings unique skills to the table, and together they form a unit you can’t help but root for.
The story is packed with twists, relentless action, and just enough unsettling moments to keep you turning pages late into the night. Shadow Sentinel is a smart, high-stakes ride that doesn’t let up.

A good mix of sci-fi and thriller. The plot is fast-paced and is interesting because of the mix of local folklore and genetic engineering. The characters are well-developed.
