All Mariamne Neige wants is to finish her thesis and get a job. Unfortunately she is a Guardian now, and her visions of the future have grown so intense she is literally blind to the world while in their grip. Another complication is her Watcher, Hanson, who is sleeping on her couch and scaring her roommates, when he's not shepherding her through the visions and calming her progressively worsening nightmares. Then the earthquakes start, warning her of an even bigger disaster-a disaster that could level her beloved city and claim both Mari's and her best friend's lives. A disaster her visions say are triggered by Hanson, even though he is sworn to protect her.
Hanson has his own problems. He joined the Watchers to atone for a life of lies, but it seems the only way he can stay close enough to Mari to protect her is to use some of his less than honest talents. She is the only witch who can ease the agony of being a Watcher, and the only woman in the world that he wants, but the distance between them grows daily. Then Mari's house is broken into and her roommates slaughtered by the Dark. In order to save Mari from the evil that hunts her, he's going to have to become more of the Dark himself, more of what frightens her, and risk losing her forever.
