20 year old Macbeth has trekked across the United States, following visions of tragedies that come to her from an unknown source. She helps where she can, putting a hand here to prevent a child from running into the street and thus preventing a grieving father from taking many more lives in his quest for vengeance. Or by rescuing a kidnapped teacher before she can be killed, thus allowing her to survive to inspire a student who goes on to create a medical miracle.
With these visions comes the ability to heal the injured. But now, Macbeth is going to discover exactly what her power comes from, and the evil that rises when she does may destroy civilization itself.
