Some truths refuse to stay hidden.When Dr. Alan Carlyle rescues a leather satchel from glacial ice, he ignites a mystery that could rewrite the entire human narrative. A university lab dates the leather to 2,400BC, but is unable to match its genome with any known species. The stitching contains polymer strands beyond the experience of modern science. Inscriptions in the leather belong to no known language. The deeper Alan digs, the greater the confusion. The growing evidence seems to indicate an ancient civilization lost to time, and perhaps to divine judgment.

Other unrelated relics begin to surface: a laser pistol embedded in sandstone from the bottom of the Atlantic, and a puzzling artifact some believe to be a spacecraft, entombed under two miles of limestone beneath the French Alps. Each bears the same haunting logo from the leather of the satchel; all point to a world that should never have existed.

While Alan gathers a team of scientists to interpret the data, he faces a private reckoning-a forgotten letter reveals that his wife, and his best friend, have a shared past about which he never knew. This betrayal fractures his faith in humanity and taints his worldview. He dives deeper into himself as he struggles with existential challenges, personal and professional, while still pondering the realities of a civilization lost to history.

When the language of the satchel is finally decoded, it reveals not just baffling science, but possibly a prophecy which serves as a warning of what humanity could again become.

The book ends with the birth of a very special baby boy, successfully cloned from ancient satchel DNA. He is destined to change the world. His story is told in the sequel volume, Incarnation, second in the Double Helix trilogy, to be released in the Summer of 2026.

Bloodline is a sweeping, speculative thriller that weaves science, faith, and human longing. Every revelation is an existential challenge, every discovery tests the soul, and the greatest proof of God may lie just under our feet.

The past is calling. Have you the courage to answer?
