An alien first contact science fiction adventure perfect for fans of Nathan Hystad, JN Chaney, and Cixin Liu.

They left a warning. We never listen.

Dr. Julian Cross has spent years chasing a theory that destroyed his career: that humanity’s ancient past holds secrets too impossible to be believed.

When his rogue excavation in the Egyptian desert unearths an artifact that predates human civilization—a seamless black obelisk that hums with alien logic—he realizes he was right about everything.
And that might get him killed.

Within hours, shadowy forces move to seize the discovery. But the artifact has already chosen its awakeners, binding itself to a small band of unlikely allies: a disgraced archaeologist, a wounded soldier, and an AI born from humanity’s darkest hour.

What they uncover will rewrite history. What they unleash may end it.

Because the Builders left more than relics beneath the sand. They left a warning—and something ancient is finally listening.

Signal Beneath the Sand is the first book in the Relic Wars series, a first contact science fiction thrill ride perfect for fans of Nathan Hystad, JN Chaney, and Peter Cawdron.
