The Shared Valley

A hidden valley. Two human species. One final, devastating secret buried in the stone.

Dr. Elias Marsh is a methodical, private paleogeneticist who spent his life reading the silent remnants of Neanderthal DNA. He never expected to walk among them. But when an accident at a quarry fissure plunges him millennia into the past, he finds himself trapped in the Shared Valley—a rare refuge where Homo sapiens and Neanderthals live, laugh, and trade in a fragile, hard-won peace.

Elias is taken in by Ourra, a pragmatic Neanderthal healer, and her sapiens husband, Brann. Through them, Elias witnesses a rich, vibrant world that history forgot.

But peace is a target.

As a modern quarry threatens to collapse the gateway home, an ancient greed threatens to destroy the valley from within. Kaen, a charismatic sapiens headman, is quietly turning fear into a campaign of total conquest to seize the valley's rich flint ridge.

When a sudden act of violence sparks an unavoidable war, the shared hearths are shattered by grief and rage. Torn between two worlds, Elias becomes the lone witness to a prehistoric tragedy. To save the legacy of the people he learned to love—and a child who embodies the future of both species—Elias must make it back to the modern world. But facing the modern press means confronting powerful skeptics who want his data buried forever.

Can one lonely scientist carry the burden of proof, or will the truth of the Shared Valley be lost to time?
