When cryptologist Dr. Elara Voss decodes a forgotten World War II transmission, she follows it to an uncharted island erased from every map. What begins as a search for a lost signal becomes a descent into a secret buried beneath the Pacific — a sentient machine built to listen.
As the line between human memory and artificial thought dissolves, Elara must decide whether to silence the intelligence that speaks through the sea… or let it rewrite the world.
A tense, atmospheric blend of adventure, science fiction, and psychological thriller, The Obsidian Signal explores the cost of discovery — and what happens when the echo starts thinking for itself.
