Bloodline: A Multi-Plot End-times Science Fiction Novel

By: Birtles, Mark

Some truths refuse to stay hidden.When Dr. Alan Carlyle rescues a leather satchel from glacial ice, he ignites a mystery that could rewrite human history. 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 reach of modern science. Inscriptions from the leather belong to no known language. The deeper Alan digs, the more the evidence points to an ancient civilization lost to time, and possibly to divine judgment.

Other impossible relics begin to surface: a laser pistol embedded in rock from the bottom of the Atlantic, and an enormous spacecraft excavated from 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, both personal and professional, still pondering the reality 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, and 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 Twilight, the second volume in the Double Helix trilogy, to be released in the Spring 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 buried beneath our feet.

The past is calling. Do you have the courage to answer?
