The intentional error. Book 3 (en Inglés) - Rick Trick

Levin lives an entirely ordinary life-until something subtly shifts.
Time begins to feel different, perception slips from certainty, and even the smallest movements seem no longer exclusively his own. A brief glance into the fog of consciousness is enough to call the familiar world into question.

It is not a conventional science-fiction novel. It is a quiet mirror, placing the reader in a state where identity, presence, and reality begin to shift without being explained. No loud revelations, no dazzling effects-only a clear focus on the imperceptible: those moments when one senses that the world is more than it appears to be.

Once read, it becomes impossible to pretend that everything is still where it belongs.
