When a mathematician encounters an impossible library containing the complete record of his life, curiosity gives way to unease. The books are meticulous and intimate, cataloging not only his past, but his apparent future. As the library's logic begins to intrude on the world beyond its walls, friendships strain, ordinary choices grow charged, and knowledge itself starts to feel dangerous. What begins as an intellectual puzzle slowly becomes a personal and moral reckoning. Blending mathematics, art theory, and philosophical fiction, A Free Will Manifold is a reflective novel about free will, determinism, and the fragile space between knowing and living.
