Deputy Hailey Pink is trapped in a dying Western town where the sheriff dismisses her warnings, and the man waiting for her at home speaks with his fists before his words. But when Hailey closes her eyes and sleeps, she flies. In the astral realm she is untouchable -- soaring over floating islands of liquid light, swimming ancient oceans alongside creatures older than memory.

But something is following her there. A shadow. A presence. A dark and ancient rage that does not belong to this world, or any other she has ever known.

The truth is stranger than any ghost story: the entity is not a monster. It is a man in another dimension who does not even know he is doing it. His unresolved anger, his consciousness leaking across the quantum web, poisoning her world like a slow and invisible plague.

To stop him, Hailey will have to become something the frontier has never seen -- a warrior of the mind, a healer of broken dimensions, and a woman willing to pay the ultimate price.
