A young woman, grappling with a devastating loss, wakes up each night feeling increasingly drained—as if someone were siphoning away her strength. In search of salvation, she travels to a seer living high in the mountains, where she discovers that she has fallen victim to an Albasty—an ancient, malevolent spirit that preys upon those broken by grief and unable to let go of the past. It assumes the guise of a person's deepest fear, gradually destroying them from within.
