An Amazon Bestseller in Technothrillers, Alternative History, and Science Fiction.

When a mysterious signal from a distant galaxy reaches a hidden SETI outpost, former Air Force intelligence officer Liam Mills finds himself pulled into a labyrinth of ancient codes, Cold War secrets, and a force capable of bending time itself.

Together with codebreaker Gina Alvarez, historian Ben Levinson, and maverick engineer Marcus Sparky Adler, Liam must uncover the truth buried across decades of hidden transmissions. What begins as a midnight decoding session spirals into a battle against an intelligence that has shaped human history from the shadows.

Blending cutting-edge science with heart-pounding suspense, The Umbra Signal is the opening chapter of the Cipherlock(TM) Sci-Fi series - a story of signals, memory, and survival at the edge of time.

Fans of Blake Crouch, Michael Crichton, and Andy Weir will be gripped by this thriller where every code unlocks a deeper mystery.

A masterfully woven Cipherlock Sci-Fi thriller that blends real-world cryptography, quantum science, and relentless suspense. A gripping debut that keeps you guessing until the final page. - American Writing Awards
