Twenty years after the Genesis Paradox, humanity has abandoned time travel.

The Chrono Gates are gone.

The Drifts have vanished.

And the power that nearly destroyed history itself has been left behind.

Then an impossible anomaly appears off the coast of Australia.

Not a portal.

Not a fracture.

A window into another Earth.

A world where the dinosaurs never went extinct.

When Kameron Jonas and his son Levi cross into the mysterious Sahul Anomaly, they discover an entire living biosphere shaped by sixty-six million years of alternate evolution. Vast titan herds roam endless plains. Ancient predators still rule. And an intelligent dinosaur-descended civilization has inherited a world humanity never knew.

But this impossible Earth carries a terrible secret.

It was never supposed to exist.

As powerful forces move to erase the anomaly forever, Kameron and Levi must answer a question larger than extinction itself:

If a world was born by accident, does it still deserve to live?

Extinction Code: Eternal Cretaceous is an epic science-fiction adventure of lost worlds, deep time, and the responsibility that comes with discovery.
