David Williams

David Williams is an Amazon Bestselling science fiction author whose debut novel, The Umbra Signal, has earned recognition as a 2025 American Writing Awards Finalist, a 2026 Cygnus Awards Long List Selection for Science Fiction, and a ★★★★★ MUST READ from Reedsy Discovery.

A veteran, technologist, and engineer, Williams blends grounded scientific speculation with emotionally driven, high-concept storytelling. Drawing on decades of experience developing advanced environmental measurement systems, signal analysis, engineering, and applied physics, he creates fictional worlds where real science and human consequences are inseparable.

He is the creator of The Umbra Trilogy, an ambitious series that explores the hidden architecture of reality through signal theory, cryptography, memory, archaeology, history, and the enduring relationships that define human identity. Written in his distinctive Cipherlock Sci-Fi™ style, the trilogy combines scientific realism, layered mysteries, and carefully planted clues that reward attentive readers while remaining deeply focused on character, sacrifice, and discovery.

Rather than treating science as spectacle, Williams uses it to explore a deeper question: How does knowledge change who we are? His novels examine how breakthroughs in physics, information theory, and history reshape people, relationships, and ultimately the nature of reality itself.

A former member of the U.S. Air Force, Williams lives in New York, where he continues to explore the intersections of physics, cryptography, information theory, history, consciousness, and the enduring mysteries of time and memory.
