Thorn Paradox. The Thorn Codex, #1

The evidence said he was mad. The facility says he was right. DI Marcus Thorn used to believe in evidence until the Hartley case destroyed him. He saw a nightmare that laughed in the face of physics: bodies twisted into impossible shapes and blood that crystallized into fractal structures. His obsession cost him his badge, his gun, and his sanity. When a mysterious recruiter offers him a second chance, Thorn expects a corporate security desk.
Instead, he is flown into the heart of a Siberian wasteland to a facility known as KV-12. Quantum Horizons is a monument to scientific hubris. In this house of glass and concrete, Thorn is surrounded by synthetic entities, a conscious mainframe that speaks in cryptic ticker tape, and research projects that bleed through the fabric of time. Thorn's job is simple: maintain the reality anchors and keep the containment seals green.
But in a place where coffee makes men disappear and the walls breathe like living tissue, the greatest threat isn't what is being researched. It's what happens when the anchors finally fail.
