Thirty years in prison. A man sealed behind concrete, steel, and silence. A tunnel carved in darkness becomes more than an escape route - it becomes a reckoning. This story is not about crime. It is about endurance. About the slow grind of time, guilt, fear, and the fragile moments where hope should not exist - but does. As the body weakens and the mind fractures, something unexpected begins to form: a movement upward, an anabasis. What unfolds is raw psychological and spiritual journey through confinement, faith, doubt, and transformation. It is a descent that becomes an ascent. A story that asks whether freedom is something taken - or something earned from within. Dark, intense, and deeply human, this book lingers long after the final page. (Previously published as Anabasis to Light).
