Synopsis
623 is a mind-bending science fiction thriller about discovery, transformation, and the terrifying realization that humanity was never alone-not in the universe, and not within reality itself.
Astronomer Jacob Hall discovers the impossible: a black hole moving directly toward the Sun, set to arrive in just over six hundred days. At first, the phenomenon appears to be a cosmic catastrophe. But the deeper Jacob investigates, the more impossible the truth becomes. The black hole is being guided. Its path is controlled by a signal. And that signal originates from an artificial structure hidden near the Sun.
As governments bury the discovery and powerful systems move to silence anyone who gets too close, Jacob is pulled into a covert world of surveillance, secret facilities, and impossible technology. Alongside his half-brother Nathan Mercer, analyst Lila, and former insider Elias Voss, he uncovers a truth far more terrifying than extinction: Earth was never the target. Humanity was.
What approaches the solar system is not a weapon, invasion, or act of war. It is a process-an intelligence beyond comprehension designed to reshape perception itself. Reality begins to fracture into layered possibilities. Contradictions coexist. The boundaries between thought, time, and existence begin to dissolve. And the signal does not simply communicate. It adapts.
As first contact unfolds in ways no human mind was built to survive, Jacob becomes the center of an irreversible transformation that could either stabilize humanity's future-or erase everything humanity once believed itself to be. Epic in scale and deeply philosophical, 623 blends cosmic mystery, psychological tension, and existential science fiction into a haunting story about evolution, consciousness, and the price of understanding the unknown.
Because the signal was never something humanity received. It was something humanity became capable of hearing.

About the Author
Michael is a science fiction author who explores the fragile line between humanity, survival, and the unknown. Blending cinematic storytelling with psychological tension, his work focuses on ordinary people forced into extraordinary circumstances-where trust collapses, systems fail, and the future of humanity hangs in the balance.
Inspired by astronomy, existential science, and human behavior under pressure, his stories combine emotional character arcs with large-scale speculative concepts designed to feel both intimate and terrifyingly possible.
When he isn't writing, Michael spends his time developing new story worlds, studying emerging science and technology, and imagining the darker possibilities hidden just beyond the horizon.
