For as long as she can remember, strange things have followed her. Shadows that move when no one is looking. Whispers from empty rooms. The unsettling feeling that something is watching from the dark. She learned to ignore it. Pretend it wasn’t real. Live a normal life. Then one of Sung Jinwoo’s shadow soldiers starts following her. As the Shadow Monarch investigates a college student who should have no connection to the Hunter world, impossible questions begin to surface. Monsters recognize her. Gates react to her presence. Shadows seem to know her long before they ever meet. The deeper they dig, the more dangerous the truth becomes. Someone erased her from history. Someone wanted her forgotten. And as lost memories begin to return, so does a secret tied to the very foundation of the System itself. Because some mistakes were never meant to survive. And some shadows were never meant to be found.
