To rescue a child of the dreamworld, a rebuilt Thomas Garner is forced to confront a truth more devastating than anything he faced before: some doors, once opened, cannot be closed without sacrifice.
Yume was never meant to exist. Born within the shifting boundaries of a world between sleep and waking, she is both miracle and anomaly-a living echo of a love that should have ended.
As the government tightens its grip and One's menace grows, Thomas begins to realize that rescuing the girl while fighting to change his wife's fate may cost him everything he has left.
