The Paleolithic Handshake

By Linden MOON

Dr. Elias Thorne was the scientist the world rejected.

Now he is the only one who knows the world is running out of time.

Exiled to a remote bunker, Thorne discovers an impossible isotope in ancient rock-Arcon-36, the cosmic fingerprint that marks every extinction in Earth's past. When its levels spike again, he calculates something horrifying: humanity is standing on the edge of a scheduled event, a precision extinction crafted by an unseen intelligence.

As a megacorporation moves to weaponize the alien signal and silence him forever, Thorne and the brilliant Dr. Maya Singh race to expose the truth. Their only hope is a desperate hack of the planet itself-a crude, chaotic burst of human-made energy meant to scramble an alien correction millions of years in the making.

The Calibration Pulse is coming.

And if they fail, humanity never existed by its own design.

Book One launches the trilogy with brutal tension, planetary-scale mystery, and a cliffhanger that will leave readers breathless for the next chapter.
