About this listen

When Death’s Clock Ticks, Can You Outrun Fate?

In the ruthless labs of Helix Innovations, geneticist Dr. Emily Harper uncovers a shocking secret: a hidden sequence in every living organism that determines the precise moment of death. Her discovery triggers a moral dilemma—whether to allow Helix to exploit it for profit, stay silent, or give it up to an organization craving control.

But as cryptic threats escalate into deadly close calls and a strange anomaly emerges, Emily realizes a sinister conspiracy lurks in Helix's shadowy corridors. Hunted by elusive figures, her quest for truth spirals into a maze of deception, where allies become enemies and every second counts toward oblivion.

In this gripping techno-conspiracy thriller, Emily faces an impossible choice: reveal the terminal gene and shatter her world, or stay silent and condemn humanity to manipulated fates. With love on the line and sacrifice the only way out, one wrong move could erase everything—forever.

This techno-conspiracy thriller is a perfect choice for Michael Crichton, Robin Cook, and Dan Brown fans.

I enjoyed this audiobook! Kat and Scott deliver strong narration that pulls you in fast and sustains tension. The characters feel real. Kat captures Emily’s resolve and strength, creating a memorable character.
The plot taps a clear fear: technology that predicts the exact moment of death. Geneticist Dr. Emily Harper makes the discovery, while powerful actors want control. She must choose: share it or surrender it. The stakes escalate, including threats to her life. Thomas grounds the thriller in real debates about science and power. The story respects your intelligence and avoids over-explaining.
It’s an engaging, suspenseful listen that left me wanting more. I hope there is a sequel.

The Terminal Gene absolutely swept me up in the most deliciously nerve-wracking way. The idea that each of us might carry a hidden “expiration date” in our genes is both fascinating and deeply unsettling—perfect sci-fi thriller material, honestly. Dr. Emily Harper is the kind of heroine I admire: intelligent, principled, and brave even when the world around her turns positively cutthroat. The narrator’s portrayal of Emily was so real, I felt like I knew her!
The corporate intrigue at Helix Innovations feels chillingly believable, and the tension builds so nicely I found myself sneaking chapters between errands. It’s dramatic, yes, but in that glossy, high-stakes way that keeps you listening. If you enjoy smart thrillers with a moral dilemma at their heart, this one is simply riveting.
