NOT ALONE IN THE DARK

On the mining world of Gehem, underground inspection teams keep a vast network of aging industrial tunnels operating beneath the planet's surface. When newly promoted inspection lead Talia Bourne discovers unexplained vibration patterns, unmapped passages, and evidence that something is moving behind sealed rock walls, routine maintenance becomes a race against an unknown intelligence.

As corporate deadlines override growing warnings, strange anomalies begin spreading beyond a single tunnel. Communication systems fail, survey maps prove dangerously incomplete, and every decision must balance engineering discipline against survival.

Grounded in realistic engineering, geology, and industrial operations, Not Alone in the Dark blends hard science fiction with psychological suspense. What begins as a technical investigation slowly evolves into a chilling first-contact mystery where the greatest danger is not what lies in the darkness—but the assumption that humanity understands it.

Perfect for readers who enjoy intelligent, atmospheric science fiction in the tradition of engineering thrillers and deep-space mysteries.
