The mascon directive

Four hundred kilometers beneath the Moon's far side, something has been counting for two billion years.

When planetary geophysicist Dr. Mara Voss catches an impossible pulse buried in routine lunar gravity data, she doesn't find a mineral deposit or a geological anomaly. She finds a ninety-kilometer artificial structure — radiating heat, holding a rhythm precise to the millisecond, and waking up.

As a private mining conglomerate races to extract it first and a black-ops command stages a kinetic strike to destroy it, Mara's team uncovers the truth: this isn't a dormant machine. It's a sentinel, built by a vanished civilization to monitor emerging species — and it began counting down the moment humanity split its first atom.

The countdown isn't to detonation. It's to judgment.

With a weapon staged, a fortune on the table, and hours on the clock, the only way to pass isn't proving what humanity can build. It's proving what humanity can choose not to do.

THE MASCON DIRECTIVE is a hard-science first-contact thriller for readers who loved The Martian's technical grip, Sea of Tranquility's lunar scale, and The Three-Body Problem's slow-burn dread — a story about restraint, discovery, and the price of being ready for what's waiting in the dark.
