The Messengers by Edward Hogan

Since her brother Johnny disappeared after injuring a policeman in a bar fight, Frances has been experiencing blackouts.  When she starts to regain consciousness,  she begins to draw.  At first the drawings are meaningless scribbles, but increasingly they have become detailed scenes containing particular people whom she has seen in town.   Then she meets Peter, who recognizes her as someone like him, a "messenger,"  doomed to create sketches of death scenes and deliver them to the people who are going to die.  If Frances refuses to pass along the drawings, someone close to her will suffer. The Messengers follows how Frances and Peter try to deal with this curse.  Creepy, thought-provoking, suspenseful.
